Can entropy change be zero for a closed system in an irreversible process? If yes under what conditions? Thanks!
Entropy change is a measure of the disorder or randomness in a system. It is a thermodynamic property that describes the amount of energy that is unavailable for work during a process.
For an irreversible process, entropy change can be calculated using the formula ΔS = ∫ dq/T, where ΔS is the change in entropy, dq is the infinitesimal amount of heat transferred, and T is the temperature of the system.
An increase in entropy change can be caused by factors such as an increase in temperature, an increase in the number of particles in a system, or an increase in disorder or randomness.
For an irreversible process, entropy change is always positive. This is because irreversible processes are characterized by an overall increase in disorder or randomness, which results in a positive change in entropy.
The second law of thermodynamics states that in any spontaneous process, the total entropy of a closed system will always increase. This means that in an irreversible process, the entropy change will always be positive, as the overall disorder or randomness of the system increases.
