Question

Derive Expression for pressure - volume work ( w = - P ex ΔV )​

Answer 1

Answer:

Work done by gases is sometimes called pressure-volume or PV work. To calculate how much work is done (or has done to it) by the gas against a constant external pressure, the formula of work done is: WORK= (w) = −Pexternal×△V : where external pressure is denoted by Pexternal.
