Is It True Hot Water Freezes Faster Than Cold?
Yes, hot water can freeze faster than cold water.
Does hot water freeze faster mythbusters
However, it does not always happen, nor has science explained exactly why it can happen.
Key Takeaways: Water Temperature and Rate of Freezing
- Sometimes hot water freezes more quickly than cold water.
This is called the Mpemba effect after the student who observed it.
- Factors that may cause hot water to freeze faster include evaporative cooling, less chance of supercooling, low concentration of dissolved gases, and convection.
- Whether hot or cold water freezes more quickly depends on the specific conditions.
The Mpemba Effect
Although Aristotle, Bacon, and Descartes all described hot water freezing faster than cold water, the notion was mostly resisted until the 1960's when a high school student named Mpemba noticed that hot ice cream mix, when placed into the freezer, would freeze before ice cream mix that had been cooled to room temperature before being placed in the freezer.
Mpemba repeated his experiment with water rather than ice cream mixture and found the sam
- does hot water take longer to freeze
- is it quicker to freeze boiling water
