A calorimeter contains 0.2 kg of water at `30^@C`. 0.1 kg of water at `60^@C` is added to it, the mixture is well stirred and the resulting temperature if found to be `35^@C`. The thermal capacity of the calorimeter is

When 0.400 kg of water at 30^(@)C is mixed with 0.150 kg of water at 25^(@)C contained in a calorimeter, the final temperature is found to be 27^(@)C , find the water equivalent of the calorimeter.

A calorimeter contains 70.2 g of water at 15.3^@C . IF 143.7 g of water at 36.5^@C is mixed with it, the common temperature becomes 28.7^@C . The water equivalent of a calorimeter is

A calorimeter contains 4.00 kg of water at 20.0^(@)C . What amount of ice at -10^(@)C , must be added to cause the resulting mixture to rach thermal equilibruim at 5.0^(@)C . Asuume that heat transfer occurs only between the water and ice.

A calorimeter of mass 50 g and specific heat capacity 0.42Jg^(-1)""^(@)C^(-1) contains some mass of water at 20°C. A metal piece of mass 20 g at 100^(@)C is dropped into the calorimeter. After stirring, the final temperature of the mixture is found to be 22^(@)C . Find the mass of water used in the calorimeter. [specific heat capacity of the metal piece = 0.3Jg^(-1)""^(@)C^(-1) specific heat capacity of water = 4.2Jg^(-1)""^(@)C^(-1) ]
