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 .
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
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)
