What is the physical significance of entropy?
Can you give me an example of how entropy works in a physical system?
Sure. Think of a hot cup of coffee placed on a table. The coffee will eventually cool down to room temperature, and the heat will dissipate throughout the room. The system, in this case, is the cup of coffee and the room it's in. As the heat spreads, entropy increases. This means that there is now less energy available to do work, as the heat has become evenly distributed throughout the system.
