1. For air at 20.0°C, there is a unique pressure above p_R = 1.00 at which the compressibility factor is the same as that of an ideal gas. Use the compressibility charts to determine this pressure.

2. For air at 20.0°C, use the compressibility charts to determine the low pressure range in which the compressibility factor of air differs from that of an ideal gas by no more than 2.00% (i.e., 1.0 ≤ Z ≤ 0.980). Is it reasonable to assume ideal gas behavior for air at pressures up to 3.45 MPa (500. psia)? 52. 200. lbm of carbon dioxide is to be put into a rigid 3.00 ft³ tank at 87.5°F. Use the compressibility factor to determine the final pressure.
