Latent heat of vaporisation

A steam engine intakes 100 g of steam at 100^(o)C per minute and cools it down to 20^(o)C . Calculate the heat rejected by the steam engine per minute. Latent heat of vaporization of steam =540 cal g^(-1) .

A calorimeter of water equivalent 15g contains 165g of water at 25^(@)C . Steam at 100^(@)C is passed through the water for some time .The temperature is increased to 30^(@)C and the mass of the calorimeter and its contents is increased by 1.5g Calculate the specific latent heat of vaporization of water. Specific head capacity of water is 1(cal)/g^(@)C .

What is latent heat ? Give is units with the help of a suitable graph , explain the terms latent heat of fusion latent heat of vaporisation.

Specific latent heat of vapourization

What do you mean by Latent heat of vapourization?

Liquid ammonia is used in ice factory for making ice from water. If water at 20^(@)C is to be converted into 2 kg ice at 0^(@)C , how many grams of ammonia is to be evaporated? (Given: The latent heat of vaporization of ammonia= 341 cal/g)

What is meant by latent heat of vaporization

Latent heat of fusion

1kg ice at 0^(@)C is mixed with 1kg of steam at 100^(@)C . What will be the composition of the system when thermal equilibrium is reached ? Latent heat of fusion of ice = 3.36xx 10^(6)J kg^(-1) and latent heat of vaporization of water = 2.26 xx 10^(6)J kg^(-1)
