When thermal energy is supplied to melt a solid, the temperature remained constant during the melting point. Explain what happened to the heat energy supplied. During melting, thermal energy absorbed is used to break the intermolecular bonds between the particles, resulting in increase in potential energy of the substance. Thermal energy is not used to cause an increase in kinetic energy of the particles, hence temperature remains constant.
