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.

When 30 g water at 50^(@)C is poured into a calorimeter at a temperature 15^(@)C , the final temperature attained is 20^(@)C . What is the water equivalent of the calorimeter?

2 kg water at 80^@C is mixed with 3 kg water at 20^@C . Assuming no heat losses, find the final temperature of the mixture

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 is found to be 35^(@)C . The thermal capacity of the calorimeter is:
