What two metals are more dense than mercury?
Osmium and gold are more dense than mercury.See the Related Questions for a complete list of the most dense elements (many of which are more dense than mercury).
Why does a cork float on water?
because cork is less dense than water
Is the angle of incidence is greater than the angle of refraction when light passes from a less dense to denser medium?
If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
What is more dence 12 or 7 cm3?
12 cm3 of Mercury is more dense than 7 cm3 of Hydrogen (at the same Temperature and Pressure), so 12 cm3 is more dense than 7 cm3.Whereas 12 cm3 of Hydrogen is less dense than 7 cm3 of Mercury (at the same temperature and pressure), so 7 cm3 is more dense than 12 cm3!Density depends upon the mass of the substance contained in the volume, so given two volumes, no statement can be made about the relative densities of those volumes without any knowledge of the mass of the volumes: density = mass/volume.Knowing the densities of the substances of the volumes, the volume is immaterial as the density is the same - density is the mass per unit volume.
What are a material whose ability to conduct electric current is greater than that of an insulator but less than that of metals?
Its the Graphite Edit: Semiconductors.
Are gases more dense than metal?
Yes, there are at least two: Iodine vapor (molar mass 254) and Radon gas (222, but not natural occurring) are heavier (and so more dense) than Mercury vapor (200 g/mol).
What two metals are more dense than mercury?
Osmium and gold are more dense than mercury.See the Related Questions for a complete list of the most dense elements (many of which are more dense than mercury).
What is mercury made of composition?
There is no exact answer to this. Astronomers have estimated that the composition of Mercury is approximately 70 percent metals and 30 percent of silicate material. It is slightly less dense than earth.
Is the earth moon less dense than mercury?
Density of our Moon: 3.346 (g/cm3). Density of planet Mercury: 5.427 (g/cm3). So, yes, it is less dense.
Is sugar a metal?
Even if metals can be less dense than the sugar, metals are solid and not of powder
What mass can float in mercury?
Most materials will float in Mercury because it is so dense. A lump of Lead will float in a bath of Mercury. The well-known metals Gold, Platinum, Tungsten, Uranium and Plutonium are more dense than mercury and would sink. More specifically, any material having a density less than 13593 Kg/m3 will float in a bath of Mercury.
Is earths atmosphere much thinner and less dense than mercury's?
No
Sugar is a metal?
Even if metals can be less dense than the sugar, metals are solid and not of powder
Will lead float in mercy?
Yes, as the lead is less dense than the mercury.
Would water or liquid mercury float?
Water floats when it is turned into ice, because in this form it is less dense (it crystallizes, and the structure expands). It also can float in combinations of liquids, for example, it is less dense than liquid mercury, but more dense than oil, so it would 'float' on the mercury. Liquid mercury is very dense, and doesn't usually float on things.
What substance is least dense rubber copper wood or mercury?
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
How do the densities of pure substances differ from the densities of mixtures?
There's no correlation between the composition of a substance and its density. Pure ethanol is less dense than potato-leek soup, but pure mercury is more dense. Potato-leek soup is less dense than pure mercury, but concrete is more dense.
