Mercury's surface temperatures are both extremely hot and cold. The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon.
From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system — that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Mercury is appropriately named for the swiftest of the ancient Roman gods. Size and Distance. If Earth were the size of a nickel, Mercury would be about as big as a blueberry. From an average distance of 36 million miles 58 million kilometersMercury is 0.
One astronomical unit abbreviated as AUis the distance from the Sun to Earth. From this distance, it takes sunlight 3. Orbit and Rotation. Mercury's highly eccentric, egg-shaped orbit takes the planet as close as 29 million miles 47 million kilometers and as far as 43 million miles 70 million kilometers from the Sun.
It speeds around the Sun every 88 days, traveling through space at nearly 29 miles 47 kilometers per second, faster than any other planet. Mercury spins slowly on its axis and completes one rotation every 59 Earth days. But when Mercury is moving fastest in its elliptical orbit around the Sun and it is closest to the Suneach rotation is not accompanied by a sunrise and sunset like it is on most other planets. The morning Sun appears to rise briefly, set and rise again from some parts of the planet's surface.
The same thing happens in reverse at sunset for other parts of the surface. One Mercury solar day one full day-night cycle equals Earth days—just over two years on Mercury. Mercury's axis of rotation is tilted just 2 degrees with respect to the plane of its orbit around the Sun.
That means it spins nearly perfectly upright and so does not experience seasons like many other planets do. Mercury is the second densest planet, after Earth. It has a large metallic core with a radius of about 1, miles 2, kilometersabout 85 percent of the planet's radius. There is evidence that it is partly molten, or liquid.
Mercury's outer shell, comparable to Earth's outer shell called the mantle and crustis only about kilometers miles thick. Mercury formed about 4. Like its fellow terrestrial planets, Mercury has a central core, a rocky mantle and a solid crust.
Kid-Friendly Mercury Mercury is the smallest planet in our solar system. Venus is hotter. Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters like our Moon.
Mercury likes to keep things simple. Mercury spins slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Mercury's surface resembles that of Earth's moon, scarred by many impact craters resulting from collisions with meteoroids and comets.
Craters and features on Mercury are named after famous deceased artists, musicians or authors, including children's author Dr.
Seuss and dance pioneer Alvin Ailey. Very large impact basins, including Caloris miles or 1, kilometers in diameter and Rachmaninoff miles, or kilometers in diameterwere created by asteroid impacts on the planet's surface early in the solar system's history.
Density of Mercury (Hg) [& g/cm3, kg/m3, Uses, Sources ...
While there are large areas of smooth terrain, there are also cliffs, some hundreds of miles long and soaring up to a mile high.Mercury is a chemical element with the symbol Hg and atomic number Mercury occurs in deposits throughout the world mostly as cinnabar mercuric sulfide. The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in thermometersbarometersmanometerssphygmomanometersfloat valvesmercury switchesmercury relaysfluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as alcohol - or galinstan -filled glass thermometers and thermistor - or infrared -based electronic instruments.
Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in scientific research applications and in amalgam for dental restoration in some locales.
It is also used in fluorescent lighting. Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet lightwhich then causes the phosphor in the tube to fluorescemaking visible light. Mercury poisoning can result from exposure to water-soluble forms of mercury such as mercuric chloride or methylmercuryby inhalation of mercury vapor, or by ingesting any form of mercury.
Mercury is a heavy, silvery-white liquid metal. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity.
Mercury - Hg
The coefficient of volume expansion is Solid mercury is malleable and ductile and can be cut with a knife. A complete explanation of mercury's extreme volatility delves deep into the realm of quantum physicsbut it can be summarized as follows: mercury has a unique electron configuration where electrons fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, and 6s subshells.Measuring the Density of Mercury with a Blood Pressure Cuff
Because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gaseswhich form weak bonds and hence melt at low temperatures. The stability of the 6s shell is due to the presence of a filled 4f shell. An f shell poorly screens the nuclear charge that increases the attractive Coulomb interaction of the 6s shell and the nucleus see lanthanide contraction.
The absence of a filled inner f shell is the reason for the somewhat higher melting temperature of cadmium and zincalthough both these metals still melt easily and, in addition, have unusually low boiling points. Mercury does not react with most acids, such as dilute sulfuric acidalthough oxidizing acids such as concentrated sulfuric acid and nitric acid or aqua regia dissolve it to give sulfatenitrateand chloride.
Like silver, mercury reacts with atmospheric hydrogen sulfide. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury spill kits also use activated carbon and powdered zinc.
Mercury dissolves many metals such as gold and silver to form amalgams. Iron is an exception, and iron flasks have traditionally been used to trade mercury. Several other first row transition metals with the exception of manganesecopper and zinc are also resistant in forming amalgams. Other elements that do not readily form amalgams with mercury include platinum.
Mercury readily combines with aluminium to form a mercury-aluminium amalgam when the two pure metals come into contact.Density is defined as mass per unit volume. The Imperial U. Note that there is a difference between pound-force lb f and pound-mass lb m.
Slugs can be multiplied with On atomic level - particles are packed tighter inside a substance with higher density. Density is a physical property - constant at a given temperature and pressure - and may be helpful for identification of substances. Below on this page: Specific gravity relative densitySpecific gravity for gasesSpecific weightCalculation examples. Specific Gravity Relative Density - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as.
Water is normally also used as reference when calculating the specific gravity for solids. See also Thermophysical Properties of Water - Density, Freezing temperature, Boiling temperature, Latent heat of melting, Latent heat of evaporation, Critical temperature Specific Gravity of gases is normally calculated with reference to air - and defined as the ratio of the density of the gas to the density of the air - at a specified temperature and pressure.
Molecular weights can be used to calculate Specific Gravity if the densities of the gas and the air are evaluated at the same pressure and temperature.
See also Thermophysical Properties of Air - density, viscosity, critical temperature and pressure, triple point, enthalpi and entropi, thermal conductivity and diffusicity, Specific Weight is defined as weight per unit volume. Weight is a force. A golf ball has a diameter of 42 mm and a mass of 45 g. The volume of the golf ball can be calculated as. The liquid may be ethyl alcohol! The mass of 0.

We don't collect information from our users.The planet named Mercury has a mass of 3. The element called mercury has a density of The mass would only have meaning for a specific amount of mercury. Density equals the mass divided by the volume. The mass is The volume is 5. The mass density of mercury is The formula for density is Mass in grams divided by Volume in centimeters squared.
Do the math. Water's density is always less than that of mercury regardless of mass. A liter of mercury has a larger mass as its density its much higher than water. Mercury would not float on water. If the density of mercury Hg is Use the density equation and solve for volume. If you know the density of mercury, you can determine the mass of a specific volume of mercury.
Mercury has a density of If we know any two variables, we can manipulate the density equation to find the third variable. When multiplying or dividing, the answer is limited to the same number of significant figures as the measurement with the fewest significant figures used in the calculation. Given an equal volume of each, mercury has by far the greater mass weight because its density is approximately Density is not the same as mass.Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.

Density of the elements
Planetary Science. Earth Sciences. Asked by Wiki User. Top Answer. Wiki User Answered Related Questions. What is the relative density of mercury?Mercury is the smallest and innermost planet in the Solar System.
Its orbit around the Sun takes This proximity to the Sun means the planet can only be seen near the western horizon after sunset or eastern horizon before sunriseusually in twilight. At this time, it may appear as a bright star-like object, but is often far more difficult to observe than Venus. The planet telescopically displays the complete range of phasessimilar to Venus and the Moon, as it moves in its inner orbit relative to Earth, which recurs over its synodic period of approximately days.
Mercury rotates in a way that is unique in the Solar System. It is tidally locked with the Sun in a spin—orbit resonance meaning that relative to the fixed starsit rotates on its axis exactly three times for every two revolutions it makes around the Sun.
An observer on Mercury would therefore see only one day every two Mercurian years. Mercury's surface appears heavily cratered and is similar in appearance to the Moon 's, indicating that it has been geologically inactive for billions of years. The planet has no known natural satellites. Two spacecraft have visited Mercury: Mariner 10 flew by in and ; and MESSENGERlaunched inorbited Mercury over 4, times in four years before exhausting its fuel and crashing into the planet's surface on April 30, Mercury appears to have a solid silicate crust and mantle overlying a solid, iron sulfide outer core layer, a deeper liquid core layer, and a solid inner core.
Mercury is one of four terrestrial planets in the Solar Systemand is a rocky body like Earth. It is the smallest planet in the Solar System, with an equatorial radius of 2, Mercury's density can be used to infer details of its inner structure. Although Earth's high density results appreciably from gravitational compression, particularly at the coreMercury is much smaller and its inner regions are not as compressed.
Therefore, for it to have such a high density, its core must be large and rich in iron. Research published in suggests that Mercury has a molten core. It is thought that these were formed as Mercury's core and mantle cooled and contracted at a time when the crust had already solidified.
Mercury's core has a higher iron content than that of any other major planet in the Solar System, and several theories have been proposed to explain this. The most widely accepted theory is that Mercury originally had a metal—silicate ratio similar to common chondrite meteorites, thought to be typical of the Solar System's rocky matter, and a mass approximately 2.
Alternatively, Mercury may have formed from the solar nebula before the Sun's energy output had stabilized. A third hypothesis proposes that the solar nebula caused drag on the particles from which Mercury was accretingwhich meant that lighter particles were lost from the accreting material and not gathered by Mercury. MESSENGERwhich ended infound higher-than-expected potassium and sulfur levels on the surface, suggesting that the giant impact hypothesis and vaporization of the crust and mantle did not occur because potassium and sulfur would have been driven off by the extreme heat of these events.
Mercury's surface is similar in appearance to that of the Moon, showing extensive mare -like plains and heavy cratering, indicating that it has been geologically inactive for billions of years.
Because knowledge of Mercury's geology had been based only on the Mariner 10 flyby and terrestrial observations, it is the least understood of the terrestrial planets. For example, an unusual crater with radiating troughs has been discovered that scientists called "the spider". Albedo features are areas of markedly different reflectivity, as seen by telescopic observation. Mercury has dorsa also called " wrinkle-ridges "Moon-like highlandsmontes mountainsplanitiae plainsrupes escarpmentsand valles valleys.
Names for features on Mercury come from a variety of sources. Names coming from people are limited to the deceased. Craters are named for artists, musicians, painters, and authors who have made outstanding or fundamental contributions to their field. Ridges, or dorsa, are named for scientists who have contributed to the study of Mercury. Depressions or fossae are named for works of architecture.
Montes are named for the word "hot" in a variety of languages. Plains or planitiae are named for Mercury in various languages. Valleys or valles are named for abandoned cities, towns, or settlements of antiquity. Mercury was heavily bombarded by comets and asteroids during and shortly following its formation 4. Mercury's surface is more heterogeneous than either Mars 's or the Moon 's, both of which contain significant stretches of similar geology, such as maria and plateaus.
Craters on Mercury range in diameter from small bowl-shaped cavities to multi-ringed impact basins hundreds of kilometers across.
