The specific latent heat of vaporization of a substance is always?
less than its specific latent heat of fusion
greater than its specific heat of fusion
equal to its specific latent heat of fusion
all of the above depending on the nature of the substance
none of the above
Uitleg
Latent heat of Vaporization is much greater than Latent Heat of Fusion for a given substance since vaporization involves more energy to separate molecules as well as to push back on the surrounding atmosphere.
