Question

Latent heat of vaporization is lower for deuterium than that of hydrogen.
If this is true enter 1, if false enter 0.

Answer 1

Latent heat of vaporization is higher for deuterium than that of hydrogen.

The properties or physical constants which are lower for hydrogen than that of deuterium are:

i) Molecular weight ii) Boiling point iii) Melting point

iv) Latent heat of fusion v) Latent heat of vaporization

vi) Bond energy vii) Activation energy
