A cooper block of mass 2.5 kg is heated in a furnace to a temperature of 500ºC and then placed on a large ice block. What is the maximum amount of ice that can melt? (Specific heat of copper = 0.39 J g –1 K –1 ; latent heat of fusion of water = 335 J g –1 ).
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Sol. Here, mass of copper block,
Rise in temperature of the copper block,
Specific heat of copper, 
Latent heat of fusion of water, 
If 
is the mass of ice melted, applying the principle of calorimetry,
Heat gained by ice 
heat lost by copper block
or
