Question:
If a liquid of mass 'm' requires thermal energy '_∆Qᵥ' completely change into gas at its boiling point without any change in its temperature, then its latent heat of vaporization can be calculated as following:

Option A):
Hᵥ = cm ∆Qᵥ
Option B):
Hᵥ =  ∆Qᵥ/m
Option C):
Hᵥ = m/ ∆Qᵥ
Option D):
Hᵥ = m∆Qᵥ

Correct Answer is Option B):
Hᵥ =  ∆Qᵥ/m
