Is the earth moon less dense than mercury?
Yes, the Earth's moon is less dense than Mercury. Mercury is one of the densest planets in the solar system, with a density about 5.4 times that of water, whereas the Moon has a density about 3.3 times that of water.
Why would a glass marble sink in water but floats in mercury?
The cause is the difference in density; the density of water is 1 g/cm3 and for mercury is 13,5 g/cm3.
Why will a block of iron float in mercury and sink in water?
A block of iron will float in mercury due to the higher density of iron compared to mercury. In water, the iron block will sink because the density of iron is higher than that of water. The buoyant force acting on the iron block is determined by the density of the surrounding fluid.
What order do you put water oil and mercury?
Water, oil, and mercury are arranged in increasing order of density. Water is less dense than oil, which is less dense than mercury. So the order would be water (less dense), oil, and then mercury (most dense).
If an object has a density of less that 1 it will?
It will float in water, and in any other fluid whose density is greater than the object's density.
A 7.40 cm3 sample of mercury has a mass of 102 g will it float in water?
No, the sample of mercury will sink in water because the density of mercury (13.6 g/cm3) is higher than the density of water (1 g/cm3), indicating that mercury is denser than water and will not float.
Why does iron float in a pool of mercury while gold sinks?
It is function of the density of the three metals. The density of iron is less than that of mercury, but the density of gold is greater. Density of iron: 7.86 g/cm3 Density of mercury: 13.53 g/cm3 Density of gold: 19.3 g/cm3 Anything more dense than a liquid will sink in that liquid, and anything less dense will float. For comparison, the density of water is only 1 g/cm3, so all three would sink in a pool of water. Styrofoam for instance is less dense than water and so it floats in water.
Will silver float in Mercury?
Yes, silver would float in mercury because silver is less dense than mercury. This means that silver would displace an amount of mercury equal to its own weight, allowing it to float on top of the mercury.
Why iron nail floats on mercury but sinks on water.?
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
Which things float on water and which sinks into it?
Objects that are less dense than water will float on it, such as wood, plastic, cork, and ice. Objects that are more dense than water will sink, such as metals like iron and steel, rocks, and most plastics. The buoyancy of an object is determined by its density compared to the density of water.
What floats best in salt water?
Anything whose density is less than that of the salt water u r taking.
How can be Mercury's average density be 5.4 times that of water?
Earth has an even greater density than Mercury. Presumably, planets a core of dense materials (for example, the density of iron is 8 times that of water), which compensates a lighter (less dense) crust.
