10. C the periodic table
The heat energy that has been required by the substance to melt a 1 mole of sample, has been given as heat of fusion. Thus, option C is correct.
Heat has been the energy that has been gained or lost by the substances in the chemical reactions.
Heat of melting
The melting has been described as the phenomenon for the conversion of solid to the liquid state. The energy has been absorbed by the solid molecules for the breaking of the bonds, and decrease in the intermolecular attractions.
The liquid state has been achieved with the loose interactions and far way molecules. The heat energy that has been required by the substance to melt a 1 mole of sample, has been given as heat of fusion. Thus, option C is correct.
