Nettet27. aug. 2024 · The Mpemba effect is the observation that warm water freezes more quickly than cold water. Hence the faster freezing. Another is that warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly. How does the mpemba effect work?
The Mpemba effect is the phenomenon where hot water freezes quicker than cold water. The Royal Society of Chemistry offered £1000 to the person or team producing the best and most creative explanation as to why this occurs. We received 22 000 entries to the competition.
