Question

Why does the temperature remain constant at the melting point?

Answer 1

The temperature remain constant during melting because the energy is used up in breaking the force of attraction b/w the particles.

Answer 2

During melting, the heat being added to a substance goes into breaking apart the"molecules" or breaking down the crystal lattice, not into raising the temperature. During the phase change all the molecules continue to have the same kinetic energy,and therefore the temperature remains constant.The same thing happens at the boiling point. The energy goes into breaking the intermolecular bonds, but theaverage kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.
