Question

Latent heat of vaporization definition and explanation

Answer 1

Answer:

Latent heat of vaporization: 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

Explanation:

latent heat is defined as:

The amount of heat that changes the state of the material without changing its temperature. Latent Heat of Vapourisation is defined as the amount of heat required to change the unit mass of liquid at boiling point into vapour under constant temperature. In general, it is the heat required to vaporise a liquid or the amount of heat to be removed from gases to condense it into a liquid.

The latent heat of vaporization of water is:

Lf = 22.6×105Jkg−1
