WebSep 25, 2024 · Where ∆S = change in entropy of the system + surroundings (the universe). ∆S = ∫dS = ∫dQ r / T For reversible adiabatic process, no heat is transferred between system and surroundings, so ∆S = 0. For Carnot engine, ∆S = Q h /T h – Q c /T c. Since Q c /Q h = T c /T h, then ∆S = 0. Quasi–static reversible process for an ideal gas WebHEAT ∆Q – energy exchanged between the system and surroundings due to temperature difference. Energy transfer – as a heat Q or work W (by means of the force acting on the system) Q and W – not a property of the system (contrary to T, p and V) Difference ∆Q–∆W=∆U is the same for all processes ! Internal energy of the system U
