    Graduate How is isobaric process physically possible?

    We have an ideal gas enclosed in cylinder whose top is covered by a piston of certain weight ##mg##. At this stage, the piston is at rest which means the force by which the gas acts on the piston (##F=PA## where ## P## is the gas pressure and ##A## is the cross sectional area of the cylinder) is...

    Graduate Understanding the Carnot cycle

    This P-V diagram summarizes the Carnot cycle. Given a working fluid whose state ##(P,V,T)## is ##(P_1,V_1,T_1)## (at point 1) where ##PV=nRT##, the working fluid undergoes a cycle of four stages and again retrieve its original state of ##(P_1,V_1,T_1)##, that is it gets back again to point 1...

    Graduate How possibly can heat flow between equally hot bodies?

    I beg to differ. Currently I'm reading Carnot's original paper: reflections on the motive power of fire. Here's a pdf link to it. In this paper, Carnot introduces the Carnot engine and Carnot cycle for the first time. And he assumed that the hot reservoir has the same temperature ##T_1## as...

    Graduate How possibly can heat flow between equally hot bodies?

    An ideal Carnot engine is composed of two reservoirs and a working fluid. The hot Reservoir and the cold one have temperatures ##T_1## and ##T_2## respectively, with ##T_1>T_2##. The working fluid is in a phase transition and has temperature ##T_1## at the start of the Carnot cycle. It undergoes...
