Water must reach 100° C before it will boil. Since hot water is closer to 100° C than cold water is, hot water will boil quicker than cold water goes once you have started to heat it.

Do you use hot or cold water to boil?

If you are looking at decreasing cooking time you would use cold water. Thermal exchange causes the water temperature to have a drastic increase. If you are just cooking the egg then it doesn't really matter.


Which boils quicker warm or cold water?

Warm water will generally boil faster than cold water because warm water is already starting with a higher temperature, so it requires less energy to reach the boiling point.


Does pasta cook faster when the water has already started to boil?

Yes, pasta will cook faster in boiling water compared to cold water. Starting the cooking process with boiling water allows the pasta to cook more evenly and quickly, resulting in better texture and flavor.


Does cold water reach boiling point faster than hot water?

Yes, from a molecular standpoint, the boiling temperature of water at standard pressure (STP), is always 100*c. Water starting at 33*c will take longer to boil than water starting at say 50*c. The temperature of water is directly proportional to the amount of thermal energy in it. The higher the temperature, the more energy the water initially has in it. If your heat source applies constant rate of thermal energy to the water, it will take less time for the warmer water to reach the amount of energy needed to change states (evaporate). But think about this... Would you rather consume boiled water that came from a cold tap, or would you rather it come from a warm, stagnant cylinder (water heater). Personally, the extra amount of time it takes to boil cold water, is well worth it.


Does ice melt faster in cold or hot water with many definitions?

It melts faster in cold

Does cold water boil faster than hot water?

No, hot water boils faster than cold water because it is already closer to the boiling point.


Does water boil faster when it is warm or cold?

Water boils faster when it is warm rather than cold. This is because warm water is closer to its boiling point, so it requires less energy to reach that point compared to cold water.


Does hot water boil faster than cold water?

Yes, hot water boils faster than cold water because it is closer to the boiling point and requires less energy to reach that temperature.


What do you need to see dose ice melt faster in water or air?

It depends on how hot/cold your water is, and how hot/cold room temperature is.


Which produces boiling water faster warm water or cold water?

I recommend putting hot water in your kettle and timing it getting to the boil, and repeating with the same volume of cold water. Then have a think about why this happens.


Does the temperature of the water, whether cold or warm, affect the rate at which it boils?

Yes, the temperature of the water does affect the rate at which it boils. Warmer water will boil faster than cold water because the molecules in warmer water have more energy and move faster, leading to a quicker boiling process.

Do flowers drink cold water or warm water faster?

cold water faster


Which boils quicker warm or cold water?

Warm water will generally boil faster than cold water because warm water is already starting with a higher temperature, so it requires less energy to reach the boiling point.


What happens when you try to boil water in subzero temperatures?

When you try to boil water in subzero temperatures, the water will freeze before it reaches its boiling point. This is because the cold temperature of the surroundings causes the water to lose heat faster than it can absorb heat to reach boiling point.


Why does hot water boils faster than cold water?

Hot water boils faster than cold water because it is closer in temperature to the boiling point. The boiling point of water is 100oC. If we had hot water at 90oC and cold water at 20oC, then the hot one would reach the boiling point of 100oC faster, since it only has 10oC more to go adn less heat needs to be added.ummm... hot water and hot water boil at the same rate...
