There are two tendencies in nature: things tend to go to the lowest possible energy (enthalph) level (delta H = negative) and the highest possible state of disorder (entropy)

Melting and boiling are physical changes.
No. The melting and boiling points of liquids vary considerably.
Melting: -259.14 C Boiling: -252.87 C
When something is melting its evaporation. When something is boiling its condensation.
Melting point -111.7C Boiling point -108.12C
The melting point is 1220.58F. The boiling point is 4566F.
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
