Formula for isothermal work
WebSep 12, 2024 · Isothermal expansion. The gas is placed in thermal contact with a heat reservoir at a temperature \(T_h\). The gas absorbs heat \(Q_h\) from the heat reservoir and is allowed to expand isothermally, doing work \(W_1\). Because the internal energy \(E_{int}\) of an ideal gas is a function of the temperature only, the change of the internal ... Isothermal processes are especially convenient for calculating changes in entropy since, in this case, the formula for the entropy change, ΔS, is simply where Qrev is the heat transferred (internally reversible) to the system and T is absolute temperature. This formula is valid only for a hypothetical reversible process; that is, a process in which equilibrium is maintained at all times.
