Introduction
• A process is reversible, if a change is brought out in such a way that the process could, at any moment, be reversed by an infinitesimal change. • In a reversible process the system and the surroundings are always in near equilibrium with each other.
Pre-Requisites:
Temperature, density, mass, volume, system and surroundings
Real Life Question:
How does temperature affect a system?

What you learn in Theory:
• A process is reversible, if a change is brought out in such a way that the process could, at any moment, be reversed by an infinitesimal change. • In a reversible process the system and the surroundings are always in near equilibrium with each other.
What you learn in Practice:
Work is said to be done when a change is brought to the system.
