A cook wants to heat 1.37 of water from 27.0 to 100.0 .If he uses the combustion of natural gas (which is exothermic) to heat the water, how much natural gas will he need to burn? Natural gas produces 49.3 of heat per gram. (For the sake of simplicity, assume that the transfer of heat is 100 efficient.)
