On page no. 57, in HC V: Laws of Thermodynamics in worked out example 1:
Is the graph made wrong? I am a bit confused since the ideal gas doesn't accept/reject any heat in bc, it should be an adiabatic process.
So, when we make the graph, P is inversely proportional to V^gamma. So, if in case, the pressure is increasing the volume should be decreasing for bc. But in the graph, both P and V are decreasing for bc.
Please help if I am interpretating something wrong. Thanks in advance.
