Answer
False, True, True, False.
Work Step by Step
False - The second law of thermodynamics states that the total entropy of an isolated system can never decrease. This is true of freezing water as, whilst the entropy of the water molecules decreases when water becomes a solid, it releases energy which increases the entropy of the surrounding molecules.
True - Freezing water is an exothermic reaction because it releases heat.
True - Freezing water results in an overall increase in entropy, as it increases the entropy of the surrounding molecules because of the energy it releases.
False - Water does not require an input of energy as it is an exothermic reaction.
