Cold water requires a higher temperature elevation than warm water does, and therefore will take longer to heat to boilinIf you start with hot water there is not enough difference in temperature from top to bottom to create an effective convection loop, because hot stuff only rises while in the presence of cold stuff to rise above. Warm water promotes a slower convection loop and hence will take longer for "ALL OF THE WATER" to hit 212 degrees.
according to scientists, the notion that a body of cold water will reach boiling temperature more quickly than an identical body of hot water under the same parameters is simply false.
This kitchen myth may have started as a way to encourage people to cook with cold water, not hot, which can contain more impurities. It may also have its origins in the fact that cold water generally gains heat more rapidly than water that is already hot, though it will not boil faster.
But under the right circumstances, the reverse phenomenon can occur, and hot water can freeze more quickly than cool water.
THE BOTTOM LINE
Cold water does not boil faster than hot water, but hot water can freeze more quickly than cool water

Which hot or cold water will freeze faster?
It has been proven that hot water freezes faster than cold water.
Does cold water drain faster than hot water?
no hot water will drip faster than cold water.This is because the molecules in hot water move around faster than in cold water. This makes it easier for molecules in hot water to slip right past other
Does a magic grow capsule open faster in hot water or cold?
Hot water
Why does your cold water have water flow but hot water has no flow?
It is a matter of density cold water is denser(compact) that hot water. thus cold water will flow faster than less dense(loose)hot water.
Why does hot water evaporate faster in cold weather?
because in hot water you will be having more fast moving molecules compared to the cold one...the more you have them,, the faster the h20 evaporate..
Why does the water become cold when filling the bath from your combination boiler?
Because you are using the Hot water faster than the boiler can produce it. Turn the tap/faucet off a bit. Get the proper sized boiler
Which hot or cold water will freeze faster?
It has been proven that hot water freezes faster than cold water.
Does Skittles dissolve faster in cold water or hot?
Probably hot water.
Does a boat sink in hot warm or cold water faster?
It sinks faster in hot water than warm or cold
What can freeze faster hot water or cold water?
cold water
What causes sugar to dissolve faster in hot water than cold water?
hot water has faster moving particales than cold water
How hot water dissolves faster then cold water?
Hot water does not dissolve. Neither does "cold". And, the grammatically correct question would be "Hot does hot water dissolve faster than cooler water."
Are the cold and hot water can dissolve faster?
Solid chemicals are dissolved faster in hot water.
Which salt dissolves faster hot or cold water?
salt dissolve faster in hot water
How do cold air and hot water make the water freeze faster?
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
Does the boat sinks faster in hot water or cold water?
hot
What kills germs faster cold or hot water?
