5 g of ice at `0^@C` is dropped in a beaker containing 20 g of water at `40^@C`. What will be the final temperature ?

A body of mass 20 g at 100^(@)C is dropped into 200 g of water at 30^(@)C . What will be the final temperature of the mixture ? Specific heat of the material of the body ="0.1 cal. G"^(-1).^(@)C^(-1).

40 g of water at 12^(@)C is kept in a container. When 50 g of water at 80^(@)C is addd to it, the final temperature becomes 46^(@)C . Find the thermal capacity of the container.

1 gm of ice at 0^@C is added to 5 gm of water at 10^@C . What will be the final temperature of the mixture?

50 g of an alloy containing 80% copper and 20% silver is heated up to t_(1)=80^(@)C and then dropped in a calorimeter of water equivalent W = 10 g containing m = 90 g of water at t_(2)=20^(@)C . What will be the final temerature of the mixture ? Specific heat capacity of copper and silver are s_(c)=0.09" cal.g"^(-1).^(@)C^(-1) and s_(s)="0.15 cal.g"^(-1).^(@)C^(-1) respectively.

An alloy contains 60% copper and 40% nickel. A piece of this alloy of mass 50 g is heated to 50^(@)C and than dropped into a calorimeter of water equivalent 10 g containing 40 g of water at 20^(@)C . Calculate the final temperature of the mixture. Specific heat of copper ="0.09 cal.g"^(-1).^(@)C^(-1) , and of nickel = "0.11 cal.g"^(-1).^(@)C^(-1)

A, B and C are three liquids. 4 g of liquids A at 60^(@)C is mixed with 1 g of liquid C at 50^(@)C , the final temperature of the mixture is 55^(@)C . Again, if 1 g of liquid A (at 60^(@)C ) is mixed with 1 g of liquid B at 50^(@)C , the final temperature of the mixture becomes 55^(@)C . What will be the final temperature if 1 g of liquid B at 60^(@)C is mixed with 1 g of liquid C at 50^(@)C ?
