How does hot water freeze faster
WebBecause the hot water is getting shocked where as the cold water is already at a cold temp. rather than the hot water which is between room temp and boiling, therefore the hot water is freezing faster because it is getting shocked meaning it needs to transfer postive temp to negetive temp :) Lawrence C. WebJan 25, 2024 · In Mpemba experiments, the water freezes over a period of minutes or hours. As the temperature drops over that period of time, weak hydrogen bonds would reform and molecules would rearrange, Katz argues. Other researchers also are debating whether the Mpemba effect exists. Scientists have struggled to produce the effect in a repeatable way.
