In an industrial process 10 kg of water per hour is to be heated from 20^@C to 80^@C . To do this steam at 150^@C is passed from a boiler into a copper coil immersed in water. The steam condenses in the coil and is returned to the boiler as water at 90^@C . How many kilograms of steam is required per hour (specific heat of steam =1 cal//g^@C , Latent heat of vapourization =540 cal//g )?

How many calories of heat will be required to convert 1 g of ice at 0^(@)C into steam at 100^(@)C

Steam at 100^(@)C is passed into 20 g of water at 10^(@)C when water acquire a temperature of 80^(@)C , the mass of water present will be [Take specific heat of water = 1 cal g^(-1).^(@) C^(-1) and latent heat of steam = 540 cal g^(-1) ]

Heat required to convert 1 g of ice at 0^(@)C into steam at 100 ^(@)C is

Stream at 100^(@)C is passed into 20 g of water at 10^(@)C . When water acquires a temperature of 80^(@)C , the mass of water present will be [Take specific heat of water =1 cal g^(-1) .^(@)C^(-1) and latent heat of steam =540 cal g^(-1) ]

Steam at 100^@C is passed into a calorimeter of water equivalent 10 g containing 74 cc of water and 10 g of ice at 0^@C . If the temperature of the calorimeter and its contents rises to 5^@C , calculate the amount of steam passed. Latent heat of steam =540 kcal//kg , latent heat of fusion =80 kcal//kg .

Steam at 100^(@)C is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.02kg at 15^(@)C till the temperature of the calorimeter and its content rises to 80^(@)C . What is the mass of steam condensed? Latent heat of steam = 536 cal//g .

The temperature of 100g of water is to be raised from 24^@C to 90^@C by adding steam to it. Calculate the mass of the steam required for this purpose.
