The physical change from a solid to a liquid.
Revise: Physical ChangesThe familiar change from solid to liquid is melting, and its reverse is freezing. A liquid changes into a gas by evaporation or boiling, while a gas changes back into a liquid by condensation.
The change from a solid to a liquid; energy is transferred to the substance while it changes state.
Do not describe every reversible change as a change of state: dissolving can also be reversible, but it is not melting.
On the ice graph, put time on the horizontal axis and temperature on the vertical axis. A flat section during melting does not mean heating has stopped.
