No. In order for water to boil, it much reach 212 degrees farenheit. If you take hot water from the tap (80 degrees) versus cold water (50 degrees) the 80 degree water will reach 212 degrees sooner then the 50 degree water.
However - and only in certain circumstances - hot water may freeze faster then cold water. Hot water evaporates faster then cold water. If you started out with the same amount of both, the hot water would begin evaporating, so you would have less water to freeze in the end.

No, cold water does not reach the boiling point faster than hot water. For instance, say you have two pots of water on the stove: one with 50 degrees F water (cold) and the other with 100 degrees F water (hot). Since water's boiling point is 212 degrees F, which of the two pots will reach 212 quicker, using the same amount of heat? The hot water will reach 212 faster than the cold, therefore boiling quicker.

If everything else is equal, then obviously the hot water will come to a boil faster because it is closer to the boiling point. To address some of the other answerers, when you add salt, it lowers the boiling point of the water - it doesn't make it reach the normal boiling point any faster.

No .. that is an old wives tale that has its roots in misunderstood chemistry. One of the things that we all at one point or another heard in some class in middle school is that pure water freezes faster than water with impurities. This can be experimented with by taking two samples of tap water and boiling the impurities out of one .... the more pure water will then freeze faster if put in a freezer AFTER the boiled sample returns to room temperature. Over time this old-timey experiment (seldom done anymore .. we can do such cooler stuff now) became simplified and misunderstood and became the old wives tale that you have heard.

Salt makes water boil slower. You add it for flavor, and only add it after the water has began to boil already.

YES IF YOU ADD SALT TO IT AND PUT A COVER ON IT...JUST LIKE HOT WATER GETS COLD FASTER THAN COLD WATER

Yea human beings say that warm water freezes swifter than chilly too. i think of it quite is a gaggle of crap. You sound like a sensible dude and your reasoning on the nice and cozy water being closer to the boiling element is sound. we'd desire to constantly all positioned up this to Mythbusters to have them discover out for advantageous.

not to sure bout cold vs. hot but i know if you add salt it will boil faster!

no because of the molecules needing more internal energy to break the surface and in hot water the molecules are already on the move

No, but if your using tap water, hot water generally isn't as clean.
