# Thermodynamics 2nd Law

The 2nd law of thermodynamics states that “in any spontaneous process, the total entropy of the universe always increases”. Yet in biological systems there are processes where there is a decrease in entropy during a reaction. Give an example of a biological process where entropy decreases (words are fine, specific reactions are not necessary). Then explain how these processes do not violate the 2nd law of thermodynamics.

Why does water freezing not violate the second law of thermodynamics? (Hint: Think in terms of a system) The entropy of the water decreases when it freezes and goes into a more ordered crystaline state. However, heat is released
