why does cold water boil faster than warm water?

Answer 1

It can be misleading to say it boils "faster." It will still take longer for cold water to boil than for warm water. However, the rate at which the colder water heats up is higher, because the rate of heat transfer is dependent on the difference in temperature between the two items - a larger temperature difference means a faster change in temperature.

Does Cold Water Boil Faster

Answer 3

cold water to boil or warm water to boil is not comparable.

However it is a tendency of every phy particle in the world to remain in Energies as low as possible to attain temperature equal to that of surroundings.

Thus when you supply heat to warm water, it's tendency is to give away the heat, as it would resist going into higher energy level.
Cold water can take heat much easily to reach normal room temperature(it's thermodynamics)
Warm water WILL boil faster than cold water, if two are timed.

it doesn't. cold water will not reach boiling temperature faster than water that is warm, all other conditions being equal. simple physics.

Answer 6

Actually heat transfer occurs fastest in a region quite close to boiling called nucleate boiling. This is where small bubbles of steam form on the element in a kettle or the hot base of a pan, rise upwards and condense in the somewhat cooler water above. This makes a 'pinging' noise as the bubbles condense and latent heat is released. This is by far the region of most efficient heat transfer where water heats up most rapidly.

Answer 7

cold water absorbs the heat energy quicker
