It has been suggested that hydrogen gas obtained by the decomposition of water might be a substitute for natural gas (principally methane). to compare the energies of combustion of these fuels, the following experiment was carried out using a bomb calorimeter with a heat capacity of 11.3 kj/oc. when a 1.50 g sample of methane gas was burned with excess oxygen in the calorimeter, the temperature increased by 7.3oc. when a 1.15 g sample of hydrogen gas was burned with excess oxygen, the temperature increase was 14.3oc. compare the energies of combustion (per gram) for hydrogen and methane.
