solidifying or freezing, releasing energy to the environment.
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.
The change is called melting.Another term is liquefaction.
When a solid is heated and changes to a liquid, the phase change is called melting.
Frost is a phase change of a gas to a solid (deposition). Water vapor turns directly to ice.
Evaporation is the change from liquid to gas. So neither it is a change.
Liquid to solid is a phase change.
The phase change from a solid to a liquid is called melting. This process occurs when a solid substance absorbs enough heat energy to break the bonds holding its particles together, resulting in the particles becoming more loosely packed and transitioning into a liquid state.
The liquid to gas phase change is vaporizing; the reverse is condensing. The other phase changes are: - solid to liquid: melting - liquid to solid: freezing - solid to gas: sublimation - gas to solid: deposition
That means liquid to/from a solid ... or liquid to/from a gas.
Solid to liquid.
melting
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
