Answer
When heat is provided to a substance then it means we are increasing the temperature of substance. Also, the molecules will start to move due to the heat provided.
As a result, intermoleculear bonds will break, that is, there will be decrease in intermolecular bonding to the molecules. Therefore, molecules will gain kinetic energy.
Thus, they will start to move rapidly from one place to another.
Hence, we can conclude that if a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, then:
its temperature increases
the number of intermolecular bonds decreases
the space between particles increases
the particles move faster
