Salt is used in countries that experience frozen winters, to remove snow from the road (it dissolves in water and decreases the freezing point of the water it's dissolved in).
Oddly enough, salt also is useful in cooking to increase the boiling point of water.
Yes, but sometimes at lower temperatures than either of the pure ingredients forming the mixture. It is call a 'eutectic'.
an endotermic one
no, food coloring doesn't cause a chemical reaction, it is essenctially like water.
I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
The reaction would be termed a chemical reaction.
It uses the chemical reaction from silicooxyxosis and creates tiny sparks, causing the molecules to slow down freezing water
The absorption of water is not a chemical reaction.

Because of chemical reaction
No, bleach and sugar water won't make an explosion but they'll cause a reaction.

Water contact can cause aquagenic urticaria, presumably due to chlorine or some other trace chemical in the water, although distilled water has been known to cause this reaction.
Foam is a solution of soap in water.

physical, because there is no chemical reaction to cause the change. it's just heat.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
Not a chemical reaction, but the formation of a water solution of hydrofluoric acid.
