A comet
due to gravity,all celestial bodies will form a solar system
They form themselves.
Droplets and rain drops
Yes, gravity does stop gases from escaping from the planet. This layer of gases is called the atmosphere and it allows humans and plants to survive.
The polar ice caps on mars are mainlt CO2 ice, frozen carbon dioxide. This is sometimes called `dry ice` on earth as it goes directly from gas to solid form with no liquid phase at normal pressures.
It is ice, in a solid form.
Frozen water; ICE
When the solid was frozen. e.g Water + ice = water.
frozen in ice form
'Dry Ice' is frozen Carbon Dioxide.
All gases can be solidified with appropiate temperatures. Then heated back to gaseous form.
Usually of liquids through the process of evaporation.
All the noble gases have solid forms that are denser than their liquid forms, so no, the liquid form is not denser than the solid form of Xe.
dry ice is the solid form of frozen carbon dioxide.
This is an odd characteristic of water and water-based drinks, that the frozen form of it is less dense than the solid form of it. If frozen water sat in water, then it would float. if any other solid form of a liquid sat in its liquid form, it would sink. Water expands when it freezes, but most elements dont. The "water" inside these cans are already pressured, so when it expands when frozen, its too much for the can to handle and it bursts.
If it's in solid form, it melts into a liquid and liquids evaporate into gases.
Pluto does have water in the form of frozen ice and methane gas and carbon monoxide. It's core is probabaly frozen ice and gas that is solid.
