question.rb1 question :copper_block_on_ice do2   kind :numerical3   describes "A copper block of %{copper_mass} is heated in a furnace to a temperature of %{copper_temp} and then placed on a large ice block. Specific heat of copper = %{copper_heat}; heat of fusion of water = %{fusion}. %{ice_melted}, in kg?"4   given copper_mass: "2.5 kg"5   given copper_temp: "500 °C"6   given copper_heat: "0.39 J g-1 K-1"7   given fusion: "335 J g-1"8   asks ice_melted: "What is the maximum amount of ice that can melt"9 end
