A 3 cubic meter tank contains 1.5 kg of a gas at 27oC and avacuum pressure of 81 kPa. What is the density and specificvolume of this gas?
A cylinder with a moveable piston contains air (an ideal gas)with a pressure of 300 kPa and a volume of 0.5 cubicmeters. The gas is heated and the piston acts against a springsuch that the relationship P=KV is always true. How much workis done by the gas if the final pressure is 750 kPa?
