Explanation :
freeze the water to ice. the delta S is negative.
becuase in water the molecules move more randomly than in a solid. if randomness is more entropy is more.
in solids randomness of molecules is decreases. so entropy decreases.
so delta S is negative (delta S < 0)
and this process is exothermic. so delta H < 0
Add Answer to:
What is delta S?
