Question

54. A copper calorimeter of mass 100 g contains 200 g
of ice at -10°C. The thermal energy is supplied
to the calorimeter and its contents at the rate of
50 calories per second. What is the temperature of
the calorimeter and its contents after ten minutes.
(Given, the specific heat of ice = 0.5 cal g-1°C-1,
the specific heat of copper = 0.1 cal g-1°C-1 and
latent heat of fusion of ice = 80 cal g-1)​

Answer 1

Answer:

200 gof ice at -10^{circ }C . The thermal energy is suppliedto the calorimeter and its contents at the rate ...
