The work done is given by the area under the P - V curve.
W = ∫ v dP
As clearly seen the Larger the value of n, the smaller is the area and so smaller is work obtained. In other words
W = ∫ v dP
\(W = \frac{{{P_1}{V_1} - {P_2}{V_2}}}{{n - 1}}\)
So, W is maximum, when n = 0 i.e. constant pressure process
W is always zero for n = ∞ i.e. constant volume process.
The heat is given by the area under the T - S curve.
dQ = ∫ T dS
or, Q = T(s2 - s1), represents the area under T-S diagram.
Hence, the Area under the process line in P - V (Pressure-Volume) and T - S (Temperature - Entropy) diagrams give work and heat interaction (Heat absorbed or Heat rejected) respectively.
