find the work done by the gas system.

Question

A mass of gases is compressed in a quasi-static process from ( 80 kPa, 0.1 m³ to 0.4 MPa, 0.03 m³.) Assuming that the pressure and volume are related by PVⁿ = constant, find the work done by the gas system.

Answer 1

Given initial pressure( ) 1 p = 80kPa

Initial volume ( ) 1 V = 0.1 m3]

Final pressure (p2 ) = 0.4 MPa = 400 kPa Final volume (V2 ) = 0.03 m3

As p-V relation pV^n = C

n ?

1. Then calculate THE w

1. W= -11.764 kJ
