2) latent heat of vapourisation

Answer 1

Mark me as brainliest

Answer:

Hii

Explanation:

here is your answer-

The "amount of heat" needed to convert "unit mass of liquid" into its "vapour state" without change in its temperature is known as "latent heat of vaporization". Example: The "latent heat of vaporization" of water is "540 cal/g/°C".

Answer 2

ANSWER :

LATENT HEAT OF FUSION :

Latent heat is the heat per unit mass required for a phase change to occur. We may think about what happens when we add ice and cold soda to glass. Since the soda is warmer than zero degrees Celsius.

LATENT HEAT OF VAPORISATION :

The amount of heat needed to convert unit mass of liquid into its vapour state without change in its temperature is known as latent heat of vaporisation.

Example: The latent heat of vaporization of water is "540 cal/g/°C".
