Well i Have actually done the test for myself hot water freezes in my freezer quicker than the cold water ....I did this about 5 years ago and I was shocked ...I used to could tell you why it would but I have lived too much life and I forgot more than I will ever know!! LOL
Boiling water freezes faster than room temperature water due to the Mpemba effect, which causes hot water to lose heat faster than cold water, thus reaching freezing point more quickly. This effect is still not entirely understood, but various factors like evaporation, dissolved gases, and supercooling have been suggested to contribute to this phenomenon.
Room temperature water freezes faster. In order to make water freeze, it has to be cooled to below 0 degrees C. Assuming that you are trying to cool this water by placing it in a subzero area (like a freezer or outside if you live in a cold place), it will take longer for the environment to absorb 100 degrees of heat than 25, since the rate of cooling will be the same for both.
Boiling water may boil off impurities which would lower the freezing point of water. For example, if your water contains 25% alcohol, if you boil half of it and then restore it to room temperature, the half that you boiled will freeze faster than the half you did not, since the boiling removes the alcohol which has a lower freezing point than water. (That's why you can safely store booze in the freezer)

Does boiling a seed make it grow faster?
No. The heat from boiling a seed would actually kill it. Soaking a seed in water before planting may help it grow faster, but the water should be room temperature.
What is one reason that room temperature water boils faster than cold water?
Room temperature water boils faster than cold water because it is closer to the boiling point, requiring less energy to reach that point. Cold water must first be heated to room temperature before it can reach the boiling point, delaying the process.
What common substance freezes at room temperature?
One common substance that freezes at room temperature is water. At 0 degrees Celsius (32 degrees Fahrenheit), water freezes and turns into ice.
Does boiling water cool to room temperature at a constant rate?
No, boiling water cools down at a non-constant rate. Initially, it cools down faster as the temperature difference between the water and the room decreases. As the water gets closer to room temperature, the rate of cooling slows down.
Can carbonated water make salt dissolve faster?
The answer depends on the temperature of both water. But salt would dissolve faster in boiling water than it could in carbonated water at room temperature.
Does boiling a seed make it grow faster?
No. The heat from boiling a seed would actually kill it. Soaking a seed in water before planting may help it grow faster, but the water should be room temperature.

Do molecules move faster in room temperature water?
Yes, molecules move faster in room temperature water compared to colder water. This is because warmer temperatures provide more thermal energy to the molecules, causing them to move and vibrate more rapidly.
What temperature is needed to separate magnesium chloride from water?
The water will slowly evaporate on its own at room temperature, but boiling temperature will do it much faster!
Which water freezes first boiling water cold water or room temperature.?
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
What common substance freezes at room temperature?
One common substance that freezes at room temperature is water. At 0 degrees Celsius (32 degrees Fahrenheit), water freezes and turns into ice.

Does hot or cold water reach room temp first?
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
Which took more time heating the water from room temperature to boiling point or boiling all the water away?
Boiling all the water away would take more time than heating the water from room temperature to boiling point. This is because during the boiling process, the water needs to be heated from boiling point to overcome the latent heat of vaporization to turn it into steam, which takes more time compared to heating it from room temperature to boiling point.
Do ice melt faster in boling water?
Yes, ice will melt faster in boiling water compared to room temperature water because the higher temperature speeds up the rate of heat transfer to the ice, causing it to melt more quickly.
Does cool water freeze faster than warm water?
No, warm water freezes faster than cool water due to the Mpemba effect, where the higher-energy molecules in warm water can transition to a frozen state more quickly. This effect can also be influenced by factors such as dissolved substances and the rate of heat transfer.
