Determine the final volume V2) of the gas P*V = constant P1 = 583.7 kPa V1 = 2.8 m3 P2 223.4 kPa QUESTION 2 A gas contained in a piston cylinder assembly undergoes a process from state 1 to state 2 defined by the following relationship and given properties. Determine the work done by the gas. P*V= constant P1 348.3 kPa V1 1.4 m3 V2 1.7 m3 and Submit to sqve and submit,. Click Save All Answers to save all answers

Explanation / Answer

1.) Relation given PV = Constant

This implies P1 * V1 = P2 * V2

V2 = (P1 * V1) / P2

V2 = (583.7 * 2.8) / 223.4 = 7.32 m^3

2) Work done by the gas from the state 1 to 2, W1-2 = P1 * V1 * In (V2/V1)

W1-2 = 348.3 * 1.4 * In (1.7 / 1.4) kJ

W1-2 = 94.67 kJ
