Q. 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? expects 1.5 kg
draft 24: failed in solution.rb, line 16 — ArgumentError: copper_block_on_ice takes ice_mass as (-heat to warm of block / latent heat of ice), a formula of quantities; don't work it out, name the quantity and the engine finds it. 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 needs
