freezing is actually exothermic... because it releases heat. but ice melting is endothermic. it absorbs heat. that's why you feel cold when you touch ice. it absorbs your body heat.

In order for a liquid to freeze, it must lower its energy (heat).
Liquids have more energy than solids (thermodynamically speaking). This energy must be lost in order for the solid to form. Therefore , freezing is an exothermic process. (EX - means out of - so the heat/energy is going "out of" the liquid).
Melting is the reverse or endothermic process (endo - means "within" or "inside" - so heat (thermos) is going inside the solid to melt it.

yes - freezing is endothermic, and melting is exothermic. freezing takes heat in, and melting releases heat. freezing and melting are opposites.

no... endothermic is when something absorbs heat... the water is not absorbing heat, it's releasing it.. that's called exothermic.

No. Freezing is not a chemical reaction.
