Question

Why do solids have high boiling and meltimg points?

Answer 1

Answer: Enthalpy and Entropy , intermolecular forces of attraction

Explanation:

Due to closely packed atoms, it requires high amount of energy to be supplied to break the bonds and to change the state.

Hence the entropy is difficult to attain negative value as Gibbs free energy is positive indicating non spontaneity , thus the enthalpy is positive.

I hope this would explain the concept...
