A gas (γ = 1.5) is compressed in an adiabatic process, then its volume changes from 1600 cm3 to 400 cm3. If the initial pressure is 150 kPa, then calculate the final pressure, and the work done on the gas.

Best answer

Given, γ = 1.5;
V1 = 1600 cm3 = 1600 × 10-6 m3 = 1.6 × 10-3 m3;
V2 = 400 cm3 = 400 × 10-6 m3 = 0.4 × 10-3 m3;
P1 = 150kPa
or P1 = 150 × 103 Pa = 1.5 × 105 Pa; P2 = ?
∵ In an adiabatic process
