There may be several possibilities, depending on the specific substance involved.
But one almost-always reliable process is the one known as "melting".
The process in which a solid changes to a liquid is called melting.
When a substance changes from a solid to a liquid, it is called melting. Freezing refers to the opposite process when a substance changes from a liquid to a solid. Condensation is the process of a gas turning into a liquid.
These are changes of phase and physical phenomenons: - solid to liquid: melting - gas to liquid: liquefaction (or condensation)
Freezing
The name for solid water is ice. It changes to a liquid when it melts.
LIQUDIFCATION!!!!!!!! Change of phase; the process is called melting.
When a solid changes to a liquid the process is called melting.
When you cool a liquid and it changes phase, it becomes a solid.
melting or liquification
condensation
Is called melting.
