Lecture - Entropy Change in Ideal Gas (part 1 of 3)

This lecture comes from a physics course on thermodynamics. In this video, students are introduced to the formula to compute the entropy change of an ideal gas when it transitions from some initial state to some final state. Since entropy is a state variable, this formula is valid for any process with those initial and final states! The free expansion of an ideal gas is used as an illustration. Part 1/3
