Question

Why is the latent heat of vaporization higher than fusion?

Answer 1

Latent heat:

1. The energy absorbed or released by a substance during a change in a physical condition that happens without affecting its temperature is referred to as latent heat.

Latent heat of vaporization:

1. Because gas molecules have the biggest intermolecular space and the force of attraction between them is nearly non-existent, the latent heat of vaporization is larger than the latent heat of fusion.
2. As a result, converting liquid to gas requires more energy.
3. Because the heat energy is solely employed to reduce the intermolecular interaction, the latent heat of fusion is lower than the latent heat of vaporization.

Hence, the latent heat of vaporization is higher than fusion.
