WebIn the free expansion of a gas, (please explain how you get the answer too) a)the work done, the heat transfer, and the change in internal energy all are zero b)the work done is zero but the heat transfer and change in internal … WebCase I : Free expansion: The gas expands into a vacuum for this process. w = 0, q = 0 Since entropy is a state function, the entropy change of a system in going from volume V1 to V2 by any path will same as that of a reversible change. Therefore, It is because from surrounding no heat is supplied. Intermediate Expansion:

WebJan 15, 2024 · Calculate the entropy change for 1.00 mol of an ideal gas expanding isothermally from a volume of 24.4 L to 48.8 L. Solution Recognizing that this is an isothermal process, we can use Equation 5.4.1 Δ S = n R ln ( V 2 V 1) = ( 1.00 m o l) ( 8.314 J / ( m o l K)) ln ( 44.8 L 22.4 L) = 5.76 J / K Isobaric Changes WebIn a free expansion, on the other hand, the gas does no work and absorbs no heat, so the internal energy is conserved. Expanded in this manner, the temperature of an ideal gas would remain constant, but the temperature of a real gas decreases, except at very high temperature.
