WebJul 20, 2024 · Consistent with prior research, we find that many students did not know that, when considering entropy in a general cyclic process (i.e., not necessarily reversible), only the entropy of the system (the working fluid) returns to the initial value. WebIsothermal processes are those which occur at a constant temperature. Temperature is directly proportional to the energy of the system, so the energy of the system must not change (ΔE = 0 and Q + W = 0). In other words, any heat added to the system must be compensated for by the system doing work.

WebReversible isothermal expansion of the gas at the "hot" temperature, TH (isothermal heat addition or absorption). During this step ( A to B) the gas is allowed to expand and it does work on the surroundings. The temperature of the gas (the system) does not change during the process, and thus the expansion is isothermic.
