WebJan 26, 2024 · Entropy change ΔS of reversible isothermal expansion is described as follows: ΔS=Q/T.Consider the process to be isothermal. Internal energy does not change with constant temperature, therefore heat absorbed by the system during reversible … WebThermal entropy (modulus an undetermined constant and in units of (3/2)Nk) as a function of R for a gas cloud contracting or expanding under the action of its own gravity. (a) Contraction. Here R < R0. Then the entropy first increases towards a maximum at R = R0 /2, and then decreases. (b) Expansion. Here R > R0. The entropy of the gas increases.
