Why entropy is highest at lowest energy?
Entropy is disorderness.So low energy means low disorderness.But why it is highest?

Entropy is only defined for equilibrium states. Perhaps you mean: why does entropy increase overall when heat flows from a high temperature body to a lower temperature body?avistein said:ok.I mean to say that why entropy is highest at equilibrium?
Another way to deal with this is to turn it around: an isolated system tends towards a situation of highest entropy. That's what we call equilibrium, because it stays there. On a macroscopic scale. On a microscopic scale small fluctuations occur in a dazzling tempo with correponding micromicroscopic fluctuations in entropy. Noticeable changes in entropy are so utterly unlikely that we can consider them absent.I mean to say that why entropy is highest at equilibrium?

The expression on Boltzmann's grave is more general than that.
I mean to say that more entropy relate to more stability.So more entropy relate to less energy. But how? more disorderness will relate to more energy
When we speak about entropy increasing we mean that there is a positive difference between the entropy of a system before and after the process (i.e. between two equilibrium states of the system). Unless the system is effectively in equilibrium during the process (ie. a reversible process) entropy is not defined during the process.Khashishi said:An equilibrium is a stationary state. If entropy is increasing, then the state isn't stationary. ...
*Entropy is overwhelmingly likely to increase whenever energy is transferred between subsystems, which is constantly happening.

Entropy at lowest energy refers to the state of a system at its minimum energy level, where the disorder or randomness of the system is at its lowest possible level. This is often referred to as the most stable state of a system.
Entropy does not change at lowest energy, as it is already at its minimum level. However, it can increase or decrease as the system moves away from this state.
The relationship between entropy and lowest energy is that entropy tends to increase as the system moves away from its lowest energy state. This is due to the fact that as the system becomes more disordered, it has more possible microstates, which leads to an increase in entropy.
In theory, entropy can reach zero at lowest energy. However, this would require a perfectly ordered system with no possible microstates, which is not possible in the real world.
The concept of entropy at lowest energy relates to the second law of thermodynamics, which states that the total entropy of a closed system will always tend to increase over time. At lowest energy, the system is in its most stable state, and any changes would result in an increase in entropy, following the second law.
