Which process describes a solid turning into a liquid when heat is added?

Explanation:
Melting is the phase change where a solid absorbs heat and becomes a liquid. At the melting point, the added energy is used to overcome the forces holding particles in a rigid lattice, freeing them to flow as a liquid. During this process, the temperature stays at the melting point until all solid has melted (in a pure substance). The other options describe different transitions: freezing is liquid turning into a solid, evaporation is liquid turning into a gas, and sublimation is solid turning directly into a gas.
