0.16 g of methane was subjected to combustion at
27∘ C in a bomb Calorimeter. The temperature of calorimeter system (including water) was found to rise by
0.5∘ C. The heat of combustion of methane at :
( i ) constant volume and ( ii ) constant pressure.
[Given: The thermal capacity of calorimeter system is 17.7 kJ K−1. (R=8.314Jmol−1K−1)]
