Processes

A piston with volume V0 = 0.20 L contains n = 0.020 mol of ideal gas with gamma factor γ = 1.4. The gas is allowed to

expand to a volume of V = 0.80 L. Compute the work done by the gas, the heat added to the gas and the change in the

internal energy of the gas for each of the following conditions.

(a) The pressure is held constant at P0 = 150 kPa.

(b) The initial pressure is P0 = 150 kPa, and the temperature is held constant.

(c) The initial pressure is P0 = 150 kPa, and the process is adiabatic.

(d) The pressure follows the curve P(V ) = P0 − a(V − V0), where P0 = 150 kPa, a = 75 kPa/L, and V0 = 0.20 L.

(e) The pressure follows the curve P(V ) = P0 + a(V − V0), where P0 = 150 kPa, a = 75 kPa/L, and V0 = 0.20 L.
