Can entropy change be zero for a closed system in an irreversible process? If yes under what conditions? Thanks!
Entropy is a measure of the disorder or randomness in a system. It is a thermodynamic property that describes how energy is distributed within a system.
An irreversible process is a process that cannot be reversed or undone. This means that once the process is completed, it cannot return to its original state without additional energy or external intervention.
In an irreversible process, entropy always increases. This is because the process involves a transfer of energy, and some of that energy is lost in the form of heat. As a result, the disorder or randomness in the system increases, leading to an increase in entropy.
The second law of thermodynamics states that the total entropy of a closed system can never decrease over time. This means that in an irreversible process, the total entropy of the system will always increase, in accordance with the second law.
Entropy and energy efficiency are inversely related. This means that as entropy increases, energy efficiency decreases. In an irreversible process, some of the energy is lost as heat, leading to an increase in entropy and a decrease in energy efficiency.
