This derivation of Carnot's efficiency formula, while it is found in most textbooks, is at best misleading and is correct only (!) for an ideal gas; it is incorrect for, say, water around 2C when absorbing heat leads to contraction not expansion. Isothermal heat absorption or rejection does no work, see Kelvin's postulate, it is a work-neutral process to keep the temperature constant in which the work is done against the stored internal energy, specifically its chemical energy as it is easily seen from Gibbs formula dU=TdS-pdV=\mu dN.

My physics exam is actually at the end of this month and this video is very helpful to me for it.

Carnot died at 37 but his work is amazing
