The heat required to change 1 gram of a solid at its normal melting point to a liquid at the same temperature is called the heat of

The amount of heat required to change 1 gram of solid to liquid at the same temperature has been the heat of fusion.

The solid has been a compact structure with the presence of tightly bonded atoms in the proximity. There has been an amount of energy that has been required to break the bond and change the state.

The state of the solid has been changed to liquid with the process of melting. The amount of heat that has been capable to convert 1 gram of substance from solid to the liquid state has been termed heat of fusion.

Heat of fusion

Explanation:

The heat required to change 1 gram of a solid at its normal melting point to a liquid at the same temperature is called the heat of fusion.

The formula for the heat of fusion is given by :

Where

n is no of moles

is molar heat of the substance

Hence, the correct answer is heat of fusion
