High order entropy
WebFeb 26, 2016 · Moreover, high entropy means that interactions between subsystems are at its maximum, which corresponds better to the definition of a living being. When two gases at different temperatures mix, entropy grows, but that doesn't mean that energy has stopped flowing. Energy is flowing at its best throughout all the molecules.
