Open in App
Solution
The correct option is B Specific latent heat of vaporization
The heat energy required to change the state of unit mass of a substance is called latent heat. As the given liquid is of unit mass (1kg) and we have to change its state into gas, therefore heat needed will be specific latent heat of vaporisation.
