Ice, of course
Frost is a phase change of a gas to a solid (deposition). Water vapor turns directly to ice.
There are three states of matter. they are solid , liquid and gas. A substance is said to be in a phase when it exhibits that state of matter. Ice is water in the solid phase. Water is ice in the liquid phase. Water vapour/steam is water and or ice in the gaseous phase.
That's it -- water. The stuff that comes out of a tap. Ice is the solid phase Water vapour is the gas phase
Water is an atypical substance in that its liquid phase is denser than its solid phase. This can be seen as ice floats in a glass of water.
Water freezes into a solid phase when it turns into snow.
Water reaches the point of freezing when it undergoes a phase transition from a liquid to a solid.
It is the gaseous phase of water
It is from the liquid phase to the solid phase. It is called freezing.
If water is found as a glacier, it is in the solid phase. Glaciers are massive sheets of ice formed from compressed snow over many years.
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
It is the gaseous phase of water
It is the gaseous phase of water
