A copper calorimeter of mass `1.5 kg` has `200 g` of water at `25^(@)C`. How much water (approx.) at `50^(@)C` is required to be poured in the calorimeter, so that the equilibrium temperature attained is `40^(@)C`? (Sp. Heat capacity of copper `= 390 J//kg-^(@)C`)

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?

A copper calorimeter of mass 190 g contains 300 g of water at 0^(@)C and 50 g of ice at 0^(@)C .Find the amount of steam at 100^(@)C required to raise the temperature of this mixture by 10^(@)C . Given that the specific heat of copperis 420J//kg^(@)C , latent heat of vaporization of water is 2.25xx10^(5)xxJ//kg and latent heat of fusion of ice is 3.36xx10^(5)J//kg .

A piece of metal of mass 112 g is heated to 100^@ C and dropped into a copper calorimeter of mass 40 g containing 200 g of water at 16^@ C . Neglecting heat loss, the specific heat of the metal is nearly, if the equilibrium temperature reached is 24^@ C . (S_(cu) = 0.1 cal//g-.^(@) C) .

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:

A calorimeter of heat capacity 100 J//K is at room temperature of 30^(@)C . 100g of water at 40^(@)C of specific heat 4200 J//kg-K is poured into the calorimeter. What is the temperature of water is calorimeter?

A calorimeter of heat capacity 100 J//K is at room temperature of 30^(@)C . 100g of water at 40^(@)C of specific heat 4200 J//kg-K is poured into the calorimeter. What is the temperature of water is calorimeter?

A calorimeter of heat capacity 100 J//K is at room temperature of 30^(@)C . 100g of water at 40^(@)C of specific heat 4200 J//kg-K is poured into the calorimeter. What is the temperature of water is calorimeter?
