Can someone explain to me briefly what the second law of thermodynamics is for and why we use it?

Hi! The second law of thermodynamics states that total entropy can never decrease over time for an isolated system, and stays constant if the system is in equilibrium or in a reversible process. We use this law because it correlates with spontaneity, as spontaneity is a function of entropy.
