I need to describe the effect of adding more air into an internal combustion engine and thought to use the equation pV=nRt.
Taking the volume of the cylinder, the constant for air and the temperature as constant (as the engine is not being modified, just the air intake is increasing)
re-aranging to give p=(nRt)/v
can i then increase n (as the higher intake increases the number of moles) to prove that pressure will increase?
or does this mean that volume will also change?
or am i way of the mark and this equation is not suited to this situation?
