ii. A mass of gas is stored in a cylinder. The gas is stored at a pressure of 1.2 MPa and the cylinder has a volume of 0.03 m3 and temperature of 100 oC , Find the mass of the gas.
The characteristic gas constant for air is 300 Jkg−1K−1.
Pressure (P)=1.2 MPa = 1.2 x106 Pa
Volume (V)= 0.03 m3
Temperature (T)= 100 oC=373 K
The characteristic gas constant for air (R) = 300 Jkg−1K−1.
To Find :
Mass of the gas(M)
Assuming air as an ideal gas , It obeys ideal gas equation P.V=M RT
Mass (M) of air is given by
