Does hot water boil faster than cold water yahoo answers?
In general, yes, hot water does boil faster than cold water. In fact, the boiling point of water increases with the increase in temperature. This means, for a given volume of water, the boiling point rises as the temperature increases.
The answer is that boiling water boils more quickly at 212 degrees Fahrenheit than at 68 degrees Fahrenheit. This is because of the expansion of water when it’s heated up. As water becomes hotter, it becomes less dense and its properties and behavior changes.
When water is heated from 68 to 212 degrees, it reaches boiling point in half the time it takes to come to a full boil from room temperature.
Does hot water boil faster than cold water in a kettle?
A kettle of boiling water boils more quickly than a kettle of cold water. This is because the surface tension of the boiling water is lower than the surface tension of the cold water. This allows the boiling water to form smaller bubbles which rise to the surface more rapidly.
If you want to make a cup of boiling water quickly, heat up a kettle of cold water and pour boiling water into it. This will not only help save a lot of time, but it will also be safer since you don� The short answer is no.
Hot water boils at 212 degrees Fahrenheit while cold water boils at approximately 212 degrees when it reaches a full boiling point. After the water reaches 212 degrees, it boils at the same rate whether it's hot or cold.
Does hot water boil faster than cold water in a pan?
Like many things in life, boiling water is quicker at a higher temperature. When you put boiling water into a pot, it will usually take less time for the water to come to a boil than it will take for cold water. For example, it may take 12 minutes for boiling water to come to a full boil, while it may take 20 minutes for cold water to come to full boiling.
This is a very common misconception. The boiling point of water is actually 212 degrees Fahrenheit. Any water that is hotter than this is boiling. That includes hot water in a saucepan, as well as hot tap water.
So the answer to the question does hot water boil faster than cold water in a pan is no.
Does hot water boil faster than cold water in microwave?
If you are wondering whether hot water will boil faster than cold water in a microwave, the answer is no. A microwave works by passing a microwave wave through the water, which causes the water molecules to vibrate. The increased energy from the vibrating water causes the water to heat up rapidly.
This heating method is very quick so you only need to heat the water for a few seconds to make it hot. Yes, boiling water in a microwave is quicker than boiling water over a stove. This is because the boiling water will undergo a process called superheating. There is no need to stand by with cold water in a kettle boiling over a stove.
The process of boiling water over a stove takes longer than the boiling of water in a microwave since the hot water is actively heating the surrounding air.
Does hot water boil faster than cold water in a pot?
Yes, hot water boils faster than cold water in a pot. If you have a pot of water on the stove, the water will start boiling at 212 degrees Fahrenheit. The boiling point of water is 212 degrees Fahrenheit because that’s the temperature water reaches when the vapor pressure is equal to the atmospheric pressure. When the vapor pressure over the water is greater than the pressure of the atmosphere, the water boils — and when the pressure of the atmosphere is greater than the vapor pressure, the water remains Hot water boils faster than cold water in a pot in the same situation. This is mainly because boiling water can transfer a good amount of thermal energy to the water in the pot, which causes the contents of the pot to also reach a high enough temperature to turn the boiling point temperature of the water.
