Completely exothermic. The atoms are losing energy to get to a solid state. Gases have most energy since they are free and unbonded to neighbouring molecules. Liquids have enough energy to stay together but still move about one another. In solids they have just enough energy just to vibrate about in a fixed point, closely bonded to neighbouring atoms. As you can there is an energy loss as you go from gas state to solid state. Loss of energy is exothermic.
Yes it is a reaction to change of heat.

Freezing(crystallization) of water is an exothermic reaction, since
the particles in the solid phase has lower kinetic energy and potential energy. For more information, you can check graphs of the heating and cooling curves.

Loss of heat = exothermic

exothermic, bcuz heat is leaving the water as it freezes

'hu hu coo' is correct (wanted to make sure you get this correct). Those terms refer to chemical changes (reactions) that give off or absorb heat. Freezing of water is a physical change.
Get an "A".

neither, no chemical reaction takes place
