7 Is It True that Hot Water Freezes Faster than Cold Water or that Cold Water Boils Faster than Hot Water?
- Author: scientificamerican.com
- Published Date: 12/08/2021
- Review: 3.77 (346 vote)
- Summary: If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm . This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases
