What is the difference between reversible process and equilibrium process in college physics? It's better to give an example.
A simple understanding of reversibility means that the entropy of isentropic process will not increase (the third theorem of thermodynamics tells us that the entropy of nature is greater than or equal to 0)
The equilibrium process is that five basic parameters, such as P V T, are not fused, and each point corresponds to each other. Imagine that two state points on a state curve are very close together, and the time between them is infinite.
