Question

What do you meant by latent heat by vapirisation

Answer 1

Answer:

Latent heat of vaporization of the liquid means the amount of heat energy absorbed when 1 kg of a substance changes from liquid to Vapour at its boiling point is called latent heat of vaporization of liquid.

example :

Change of water into gas requires a certain heat level so that it can broke its loosely arranged particle of liquid(water ) to change its state to gas.

Answer 2

Answer: 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
