Short Answer Practice:

Explain why "350 m3(STP)/h of nitrogen at 25oC and 3.5 atm" looks like a contradiction but is not one.

Short Answer Practice:

If the compressibility factor of a gas (of known temperature and molar volume) in a cylinder is 2, what is the ratio of the actual pressure in the vessel compared to that if you assumed an ideal gas?
