What causes matter to change from one state to another?

Answer 1

To change a solid into a liquid, you melt it. To change a liquid into a gas, you boil it. To change a gas into a liquid, you condense it. To change a liquid into a solid, you freeze it.

Some solids cannot be melted. Complex molecules may break down or burn before they melt e.g. wood, meat.

Answer 2

Yes.

solid changing to a liquid = melting (or "fusion")

solid to gas = sublimation

liquid to solid = freezing ("solidification")

liquid to gas = vaporization ("evaporation", "boiling")

gas to solid = deposition

gas to liquid = condensation

Answer 3

Temperature or pressure are two ways to change matter from one state to another. Heating something can make it turn in to a gas while cooling something can make it turn in to a solid.

Answer 4

Matter changes from one state to another by adding or removing energy in the form of heat, to either melt, boil, condense or freeze the matter.

Answer 5

temperature
