Liquid ammonia 1s used in ice factory for making ice from water. If water at ` 30^(@)C` is to be converted into 800 g ice at ` 0^(@)C`, how many grams of ammonia are to be evaporated? (Given: Latent heat of vaporisation of ammonia = 341 cal/g)

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 are to be evaporated ? (Given : The latent heat of vaporization of ammonia = 341 cal //g )

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 are to be evaporated? (Given: Latent heat of vaporisation of ammonia= 341 cal/g)

Calculate the amount of heat required to convert 80g of ice at 0^(@)C into water at the same temperature . ( Specific latent heat of fusion of ice = 80 cal //g )

M g of ice at 0^@C is to be converted to water at 0^@C . If L is the latent heat of fusion of ice, the quantity of heat required for the above operation would be

Find the heat required to convert 20 g of iceat 0^(@)C into water at the same temperature. ( Specific latent heat of fusion of ice =80 cal//g )

Calculate change in entropy when 5g of pure ice melts to form water at 0^(@)C Given latent heat of ice is 80cal//g at 0^(@)C .

A thermally insulated pot has 200 g ice at temperature 0^(@)C . How much steam of 100^(@)C has to be mixed to it, so that water of temperature 40^(@)C will be obtained? (Given: Latent heat of melting of ice = 80 cal/g, latent heat of vaporisation of water = 540 cal/g, specific heat of water = I " cal/g " ^(@)C)
