Question

41. A copper calorimeter of mass 100 g contains 200 g
of ice at a temperature of -10°C. Heat is supplied
to the system containing calorimeter and ice at a
constant rate of 50 cal s-1. Find the time required
to raise the temperature of the system to 50°C.
[Neglect the loss of heat to the surroundings.] Take
specific heat capacity of copper and ice as 0.2 cal
g-1 °C-1 and 0.5 cal g-1 °C-1. Take latent heat of
fusion of ice as 80 cal g- and specific heat capacity
of water as 1 cal g-1 °C-1.
