Calcualte the mass of stea that should be passed though 60 g of water at `20^(@)C`, such that the final temperature is `40^(@)C`. (take specific latent heat of steam is 2250 J `g^(-1)`).

The amount of steam at 100^@ C that should be passed into 600 g of water at 10^@ C to make the final temperature as 40^@ C will be

Calculate the amount of ice, which is sufficient to cool 45g of water, contained at 30^(@)C , such that the final temperature of the mixture is 10^(@)C . (Take specific latent heat of fusion of ice is 336" J "g^(-1) )

How much steam at 100^(0)C is to be passed into water of mass 100g at 20^(0)C to raise its temperature by 5^(0)C ? (latent heat of steam is 540cal/gm )

Calculate the mass of ice needed to cool 150 g of water contained in a calorimeter of mass 50 g at 32^@ C such that the final temperature is 5^@ C. Specific heat capacity of calorimeter = 0.4 J g^(-1)^@C^(-1) , specific heat capacity of water = 4.2" J "g^(-1)""^@C^(-1) , latent heat capacity of ice = 330 J g^(-1) .

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 )

40 g of water at 60^@ C is poured into a vessel containing 50 g of water at 20°C. The final temperature of mixture is 30°C. Taking the specific heat capacity of water as 4.2 J g-K-1, calculate the heat capacity of the vessel.

An amount of water of mass 20 g at 0^(@)C is mixed with 40 g of water at 10^(@)C . Final temperature of mixture is
