A copper block of mass 2.5 kg is heated in a furnace to a temperature of 500 °C and then placed on a large ice block. Specific heat of copper = 0.39 J g⁻¹ K⁻¹; heat of fusion of water = 335 J g⁻¹. What is the maximum amount of ice that can melt, in kg?

No single law in using: gives this formula of block.heat_to_warm and ice.latent_heat; name what is asked and the engine chains the laws it needs1718  conclusion "The copper cools to the melting point of ice, giving up heat that melts ice; the maximum melt occurs when all the copper's heat goes into melting."19end
