When you apply heat energy to a substance, where does the energy go? think about the law of conservation of energy.

When you apply heat to a substance, the heat goes into breaking the intermolecular bonds in the substance because the kinetic energy of the molecules of the substance is increased.

In every state of matter, the particles of the substance are held together by intermolecular bonds.

These intermolecular bonds are responsible for the physical properties of matter.

According to the law of conservation of energy, energy is neither created nor destroyed but is converted from one form to another.

Hence, when you heat a substance, the thermal energy supplied is converted into the kinetic energy of the molecules of the substance.
