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 mass 50 gm and specific heat capacity 0.42 J g^-1 ^@C^-1 contains some water at 20^@ C. A metal piece of mass 20 gm 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. (specific heat of metal piece= 0.3 J g^-1 ^@C^-1 specific heat of water = 4.2 J g^-1 ^@C^-1 )

A copper calorimeter of mass 100 gm contains 200 gm of a mixture of ice and water. Steam at 100°C under normal pressure is passed into the calorimeter and the temperature of the mixture is allowed to rise to 50°C. If the mass of the calorimeter and its contents is now 330 gm, what was the ratio of ice and water in beginning? Neglect heat losses. Given : Specific heat capacity of copper =0.42xx10^3 J kg^(-1) K^(-1) . Specific heat capacity of water =4.2 xx10^3 J kg^(-1) K^(-1) Specific heat of fusion of ice =3.36xx10^5 J kg^(-1) Latent heat of condensation of steam =22.5 xx 10^5 J kg^(-1)

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 )

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) ]

100 ml of water at 20^(@)C and 100 ml of water at 40^(@)C are mixed in calorimeter until constant temperature reached. Now temperature of the mixture is 28^(@)C . Water equivalent of calorimeter is
