A pressurised air tank supplies compressed air to an air engine. When the air engine is not running the absolute pressure in the tank is 300 bar and the temperature of the air is 60°C.

Typical gas molecular values:

Gas Symbol Mr (g/mol)

Hydrogen H2 2

Oxygen O2 32

Carbon Dioxide CO2 44

Methane CH4 16

Nitrogen N2 28

Air (none available) 28.96

Calculate:

(a) The temperature of the air in the high pressure air tank when the air engine starts and the absolute pressure in the tank drops to 270 bar. Volume remains constant.

(b) The mass of air in the pressurised air tank using the temperature and pressure from part 1 (a).

Note: 1 m3 = 1000 litres

1 bar = 1 x 105 Pa

R is the universal gas constant and is always 8.314 J·K-1·mol-1

Tank volume = 450 litres

pV = (m/Mr)RT
