During the compression stroke of a certain gasoline engine, the pressure increases from 1.00 atm to 20.5 atm. The process is adiabatic and the air–fuel mixture behaves as a diatomic ideal gas.
(a) By what factor does the volume change?
Vfinal = Vinitial
(b) By what factor does the temperature change?
Tfinal = Tinitial
Assume the compression starts with 0.016 mole of gas at 26.5°C.
(c) Find the value of Q that characterizes the process.
J
(d) Find the value of ΔEint that characterizes the process.
J
(e) Find the value of W that characterizes the process.
J
