60 cubic feet of air at 30 PSIG and 50 degrees F is compressed to 80 PSIG and 110 degrees F. What is the final volume?

Assuming the air is ideal, you can use the formula
P1 * V1 / T1 = P2 * V2 / T2
where
P1 and P2 = initial and final pressures respectively (psi)
V1 and V2 = initial and final volumes respectively (ft^3)
T1 and T2 = initial and final absolute temperatures respectively (Rankine)
