Question

A calorimeter is made of a metal X and weighs
250g. It contains 200g of liquid L at a temperature
of 28°C. A piece of a metal X of mass 500g at
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 45°C, calculate T
Take specific latent heat of vaporisation of Lata
boiling point of 105°C to be 2.1 x 10 kgl. the
specific heat capacity of L as 4200 Jkg' K" and
the specific heat capacity of X as 420 Jkg K.​

Answer 2

Answer:

A calorimeter is made of a metal X and weighs

250g. It contains 200g of liquid L at a temperature

of 28°C. A piece of a metal X of mass 500g at

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 45°C, calculate T

Take specific latent heat of vaporisation of Lata

boiling point of 105°C to be 2.1 x 10 kgl. the

specific heat capacity of L as 4200 Jkg' K" and

the specific heat capacity of X as 420 Jkg K.

Explanation:

A calorimeter is made of a metal X and weighs

250g. It contains 200g of liquid L at a temperature

of 28°C. A piece of a metal X of mass 500g at

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 45°C, calculate T

Take specific latent heat of vaporisation of Lata

boiling point of 105°C to be 2.1 x 10 kgl. the

specific heat capacity of L as 4200 Jkg' K" and

the specific heat capacity of X as 420 Jkg K.
