Question

Constant volume combustion vs constant pressure combustion

Answer 1

Answer:

A equation of state often relates to three parameters, temperature T, volume V, pressure P. Taking ideal gas as an example, PV=nRT.

For a constant volume situation, it becomes to P=F(T).

Pressure is only relates to temperature. T goes high, pressure in a chamber goes high, vice versa. (Volume of this chamber does not change.)

For a constant pressure situation, it becomes to V=F(T).

Volume is only relates to temperature. T goes high, volume of  a chamber goes bigger, vice versa. (Pressure of this chamber does not change.)

Answer 2

$\huge\bold\red{HOLA!!}$

When you add heat at constant volume, the pressure is allowed to rise, and all of the energy added can be ... In contrast, constant pressure combustion has increasing volume which may not favor the flame
