Essential Chemistry for IGCSE - Particles And Purification (Section 4 - No. 16)
During melting, what happens to the energy absorbed by the substance?
It increases the kinetic energy of the particles.
It increases the potential energy, breaking intermolecular bonds.
It decreases the kinetic energy of the particles.
It changes the substance's chemical composition.
Explanation
Energy absorbed during melting is used to overcome intermolecular forces, increasing potential energy.
