A chair is usually solid, because matter usually exists in one of three states or phases: solid, liquid, or gas.
Water can exist in all 3 states, liquid, solid and gas. At room temperature, water is liquid. When it is below zero degrees celsius, it becomes ice, a solid. When it is above 100 degrees celsius, it becomes steam, a gas.
When any liquid changes to a solid it as too be frozen or cooled to such a state where the molecule join together to make one uniform state (aka soild)
it is a gas but when it condenses it becomes a liquid
a liquid turns into gas when it is heated...
To get a solid to a liquid you have to apply heat and melt it, and to get a liquid to a gas it has to evaporate. If you are talking about a solid going into a gas, then I don't know.
