which boils quicker, warm or cold water?

Answer 1

warm water

Temperature at which the vapor pressure of the liquid equals the pressure of the surroundings is the boiling point

Since warm water has a temperature nearer to 100oC than cold water ,warm water boils quicker.

BUT IT ALSO DEPENDS UPON THE RATE OF HEATING, INTENSITY OF FLAME, VESSEL OF HEATING.

Answer 2

If you are referring to overall duration. Warm water boils quicker but altitude affects the time for both cold and warm. The reason people believe cold water boils quicker is because the energy inside of atoms become exicted at a quicker pace when the water is cold. Simple chemistry of getting those atoms moving. But in terms of acceleration it will break over the boiling point quicker from a cold temperature, but in terms of bringing water from 48 degrees to 86, to 105, etc. It will take much longer with cold water. I was taught the same thing by my one of my engineering teachers at University.

Answer 3

Cold water boils Quicker.

Answer 4

Warm water, since the temperature of the warm water is closer to its boiling point(100 degree C).

Answer 5

cold water, because the temperature increases at an exponential rate, thus if you start with less amount of temperature then you can get a faster rate of evaportion/boiling- which is due to electrons transferring from fire to the pot then to the water molecules that form bubbles due to the greater energy than the pressure acting upon it

Answer 6

Assuming everything about the state and enviromnent of warm and cold water is static, as none has been specified, neither will boil.

Answer 7

It's according to how you do it. Cold water sometimes boils quicker:

Answer 8

Cold water. Don't know why it's just one of those freak things of nature i guess.

Answer 9

teacher told us colder. said like roller coaster, farther one away(up) will go faster. sorry-was a while ago
