A copper plate of mass 2 kg is heated to a temperature of 600oC and then placed on large ice block at 0 oC. Calculate (i) the maximum quantity of heat that the copper plate can transfer to ice block and ii) the maximum amount of ice it can melt. Given: Specific heat of capacity of copper = 390 J kg–1 K–1 and latent heat fusion of water = 333 × 103 J kg-1 .
