During the transformation of matter from the solid to the liquid state, the heat supplied does not produce a temperature increase because
the heat energy is quickly conducted away
the heat capacity has become very large as the substance melts
the heat gained is equal to the heat lost by the substance
all the heat is used to break the bonds holding the molecules of the solid together
Forklaring
