Whitepunk [10]

Entropy change is defined only along the path of an internally reversible process path.

<h3><u>What is Entropy Change </u>?</h3>
  • Entropy is a measure of a thermodynamic system's overall level of disorder or non-uniformity. The thermal energy that a system was unable to use to perform work is known as entropy.
  • Entropy Change is a phenomena that measures how disorder or randomness have changed inside a thermodynamic system.
  • It has to do with how heat or enthalpy is converted during work. More unpredictability in a thermodynamic system indicates high entropy.
  • Entropy is a state function, hence it is independent of the direction that the thermodynamic process takes.
  • The rearranging of atoms and molecules from their initial state causes the change in entropy.
  • This may result in a decrease or rise in the system's disorder or unpredictability, which will, in turn, result in a corresponding drop or increase in entropy.
