D) for … 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
