Webwhere ΔS is the change in entropy, δQ is the heat transferred, and T is the temperature. For an isothermal process, the temperature remains constant, so ΔS = Q/T. We can find the heat transferred, Q, using the first law of thermodynamics: ΔU = Q - W. where ΔU is the change in internal energy and W is the work done. For an isothermal ... WebIn an internally reversible, isothermal process, our definition of entropy can be used AND T pops out of the integral because it is constant. That leaves with just T times the integral of dQ on the RHS and the integral of dQ is just Q. It doesn’t get much easier than that ! So, for an internally reversible, isothermal process, ΔS is just Q ...
