During the compression stroke of a certain gasoline engine, the pressure increases from 1.00atm to 20.0atm.
If the process is adiabatic and the fuel air mixture behaves a a diatomic ideal gas
a) by what factor does the volume change
b) by what factor does the temperature change?
c) assumignt he compression starts with 0.0160mol of gas at 27.0 C, find the values of Q,W, and E<sub>int</sub> that characterize the process

P*V^(7/5) = constant for adiabatic compression of a diatomic gas.
(P2/P1) = (V2/V1)^-7/5 = 20
The volume ratio is (20)^(-5/7)
Once you have the P ratio and the V ratio, use the gas law to get the T ratio
PV/T = constant
P2 V2/T2 = P1 V1/T1
T2/T1 = (P1 V1)/(P2 V2)
(P2/P1) = (V2/V1)^-7/5 = 20
