The specific heat ratio for a diatomic gas is 7/5.
Assume an adiabatic process with
P*V^1.4 = constant
b) P2/P1 = (V1/V2)^1.4
a) Once you have P2, use the ideal gas law for T2.
You do the rest.
Air in a diesel engine cylinder is quickly compressed from an initial temperature of 21.1°C, an initial pressure of 1.00 atm, and an initial volume of 670 cm^3 to a final volume of 44.5 cm^3.
a) Assuming the air to be an ideal diatomic gas, find the final temperature (in K).
b) Assuming the air to be an ideal diatomic gas, find the final pressure
