Dear All,
I am trying to understand the concept of "entropy" in thermal engineering point of view.
I have basic idea about "entropy" i.e. the change in entropy is used to determine the direction in which a given process will proceed.
However following two more definition (of entropy generally available in textbooks) are confusing and not allowing me to really understand it.

- “Entropy can also be explained as a measure of the unavailability of heat to perform useful work”. Or “Entropy quantifies the energy of a substance that is no longer available to perform useful work”.
- “Entropy is sometimes referred to as a measure of the inability to do work for a given heat transferred.”
