The combustion of a fuel usually results in an increase in pressure when the volume is held constant, or an increase in volume when the pressure is held constant, because of the increase in the number of moles and temperature. The increase in pressure or volume will be maximized when the combustion is complete and when it occurs adiabatically with the theoretical amount of air. Consider the combustion of methyl alcohol vapor, CH3OH (g), with a stoichiometric amount of air in a 1.5 L combustion chamber. Initially, the mixture is at 25°C and 101 kPa.
a)max pressure that can occur if comb. is constant volume
b) max volume if comb is constant pressure
