The temperature of 100 g 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.

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.

(a) The temperature of 100 g of water is to be raised form 10^@C to 40^@C by adding steam at 100^@C to it. Determine the mass of the steam required for this purpose. (b) How much steam at 100^@C will just melt 2700 g of ice at -10^@C ?

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 )?

The quantity of heat required to raise the temperature of 2000 g of water from 10^@C to 50^@C is

Steam at 100^@C is allowed to pass into a vessel containing 10g of ice and 100 g of water at 0^@C until all the ice is melted and the temperature is raised to 50^@C . Neglecting water equivalent of the vessel and the loss due to radiation etc. Calculate how much steam is condensed.

1g of ice at 0^@ C is mixed 1 g of steam at 100^@ C . The mass of water formed is

Steam at 100^(@)C is added slowly to 1400 gm of water at 16^(@)C until the temperature of water is raised to 80^(@)C . The mass of steam required to do this is ( L_(V) = 540 cal/g)

A steam engin intakes 100g of steam at 100^((0))C per minute and cools it down to 20^((0))C . Calculate the heat rejected by the steam engine per minute. Latent heart of vaporization of steam =540 cal g^(-1) .
