Why does ∆S = 0 for a reversible process, but for a reversible isothermal process, ∆S is given by nRln(Vf/Vi) (or other variations of that equation)?
In a reversible isothermal process, the temperature remains constant throughout the process. Entropy change refers to the change in the distribution of energy in a system during this process.
The equation for calculating entropy change in a reversible isothermal process is ∆S = Q/T, where ∆S is entropy change, Q is the heat transferred, and T is the temperature.
Entropy change is a measure of the amount of energy that is lost or gained during a reversible isothermal process. It indicates the direction and extent of the change in energy distribution.
Yes, entropy change can be negative in a reversible isothermal process. This means that the energy in the system is becoming more ordered and less dispersed.
The efficiency of a reversible isothermal process is directly affected by entropy change. A lower entropy change means a more efficient process, while a higher entropy change means a less efficient process.
