Want this question answered?
it only takes about 3 minutes to dissolve sugar in hot to boiling water. When it could take about a hour for cold water.
Cold air and hot water makes water freeze faster simply because the hot water is steaming and so the result is that there is less water to freeze. hot water = steam = less water less water = faster freeze cold air = faster freeze
Hot water has the energy(heat) to make the change go faster
Cold water makes plaster set slower. Hence, hot water makes it set faster.
cold air
Cold water.

An easy way to make water cold is to put it in the refrigerator. If this is not possible, adding colder water would make water colder. Actually, adding ice would make this process faster, as it is colder than cold water. And dry ice would make it cold even faster than ice (but dry ice is dangerous- be careful).
Run cold water over it.

sunlight will
yes it makes us go alot
The question does not make sense. Very bad grammar.
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.
My fiance and I did an experiment with hot and cold water to see which one would make ice cubes faster. Honestly they froze at about the same time. He was taught that because its hot the molecules come together faster in the cold air, but during the test it was equal. As for the salt water I would think that would come in last.
