b) Assuming the air to be an ideal diatomic gas, find the final pressure.

**drwls**, Tuesday, December 27, 2011 at 7:58amDue to the quick compression, the process will be adiabatic. For such a process,

P*V^g = constant

Do part (b) first with the above equation.

P2/P1 = (V1/V2)^g

Once you have P2, use the ideal gas law for T2.

For a diatomic, g is the dimensionless number 7/5.
