Answer to Question #2978 in Molecular Physics | Thermodynamics for Jack Tredrea
where V1-the initial volume, V3 -the final volume.
From the equation of state, if our substance is a gas we can get an approximate value of the expansion work using the ideal gas equation of state
Since T=const, we can say that nRT=p3V3
also from the properties of ln-function
So we have
A=p3V3*ln(V1/V3) that's exactly what ur teacher wrote.
