Raisins plump up more quickly in hot water because the molecules in hot water move quicker than molecules in cold water so the hot water molecules diffuse quicker into the raisin.
it soaks up and turns softer .but does not turn back to a grape it soaks up and turns softer .but does not turn back to a grape

Solids dissolve a lot more quickly in hot water because the heat breaks up the particles more quickly, where as the cold would make the particles stay stronger/closer together :)
No. Cold water absorbs more quickly into the body than warmer water, making chilled water preferable for hydration.
I can only assume since they are water bound (and water can be very cold) That it can be 'water proof' and dries quickly. And keeps the cold out. (:
Cold water, and burn cream
I had the same quesiton on a worksheet in my Chemistry class .... "Which metal reacts quickly with when water when it is finely powdered?" The answer is Magnesium .
yes, it freezes faster because it loses its temperature more quickly; while cold water maintains its temperature better
neither. the water needs to be boiling to create gas. Hot water will not create gas and cold water will not create gas. Yes, hot water will create gas more quickly than cold if boiled tho
shocking.
