The second law of thermodynamics states that the total entropy of an isolated system always increases over time, or remains constant in ideal cases where the system is in a steady state or undergoing a reversible process. The increase in entropy accounts for the irreversibility of natural processes, and the asymmetry between future and past.

Second law of thermodynamics states that any natural system tends to disorder. That is, the total entropy of the universe will tend to increase over time.

This is the only physical law that gives an actual notion of the quantity "time", as time is unidirectional, and all systems WILL tend to deviate from orderliness and end up in a disordered state.

For example, take a very crude case. Two tanks seperate by a stopcork have two different gases. If the stopcork is removed, as time progress, the two gases mix up and go into a disorderly state. It is nearly impossible for all the molecules of one gas to be seperated from the other gas naturally by itself, unless external intervention takes place.
