I heard about this thing called the Mpemba effect where hot water can freeze quicker than cold water under certain conditions. How does that even work?
In: Chemistry
The Mpemba effect, where hot water freezes faster than cold water under certain conditions, is thought to happen for a few reasons. One theory is that hot water evaporates faster, reducing the volume of water that needs to freeze. Another idea is that the temperature difference between hot water and the freezing environment can increase the rate of cooling. Also, hot water can lose its gas content more quickly, leading to a change in its properties that might affect freezing times. The exact cause is still a topic of research, but these factors contribute to the curious phenomenon.
