What is the physical significance of entropy?
That's interesting. Can you give me an example of how entropy works in thermodynamics?
Sure! In a steam engine, the heat energy in the steam is converted into useful work by driving the pistons that power the engine. However, as the steam is used to do work and is expelled from the engine, it becomes more disordered and its entropy increases. This means that there is less heat energy available to do work in future cycles.
