An ideal gas undergoes a cyclic process ...

An ideal gas undergoes a cyclic process `(V,P) to (3 V, P) to (V, 4P) to (V, P)` along straight lines on the P - V plane. Calculate the work done in the process.

Text Solution

Verified by Experts

Area of the cycle = `1/2 xx "base" xx "height"`
`=1/2 (3V - V) (4P - P) = 3 PV`
As the cycle is anticlockwise, the work done = -3 PV.
