Acalorimeter is made of metal x and weighs 250g. it contains 200g of liquid l at a temperature of 28oc. a piece of metal x of mass 500g at a temperature t is put in the calorimeter and 5g of l is boiled off as vapour. if the temperature of the calorimeter and its content is 45oc, calculate t. take specific latent heat of vaporization of l at a boiling point of 105oc to be 2. 1 × 10^6 jkg^-1, the specific heat capacity of l as 4200 jkg^-1, the specific heat capacity of l as 4200 jkg^-1 k^-1 and the specific heat capacity of x as 420 jkg^-1 k^-1.
