Changes in Entropy that occur when an Ideal Gas is subjected to both reversible and irreversible operations
For an Isothermal Operation
Entropy For An Irreversible Operation
Consider a gas changing from
. Now since the Function of State depends upon the values of P:V:&T at 1 & 2 and is independent of the process.
