For X ⇒ Y, the process is isobaric. Since the gas is expanding, W < 0 and since the temperature is increasing, ∆U > 0 and ∆U = Q + W so Q > 0 (it is also true because process XY lies above an adiabatic expansion from point X) commented Sep 9, 2024 by Hemavathi (10 points)

For a spontaneous process, which of the following is always true : … WebApr 18, 2015 · delta(q) = delta(u) + w delta(q) is the change of heat of the system, delta(u) is the change of internal energy of the system and w is the work done by the system. …

http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/firlaw.html WebAlternatively you could reason using the formula: d U = d Q − d W (using your notation conventions, were U is internal energy, W is work and Q is heat added to the system) d W = P d V. Therefore. d U = d Q − P d V. Therefore if d V (change in volume) is positive, d U (change in internal energy) is negative. Share.
