Why Does Cold Water Freeze Faster Than Hot at Kraig Ronald blog

Why Does Cold Water Freeze Faster Than Hot. A more mundane explanation is that hot water evaporates faster than cold, decreasing its volume and thus the time it takes to freeze. But logic triumphs when it comes the plain. The physics of why hot water sometimes freezes faster than cold water. When water is hotter than 80 degrees c, the rate of cooling by rapid vaporization is very high because each evaporating gram draws at least 540 calories from the water left behind. The mpemba effect is a physics concept that postulates that when hot water and cold water are placed in the identical freezing environment, the hot water will freeze faster than the cold water. Cold water also could contain more dissolved gases, which lower its freezing point. It seems obvious that the answer should be no, because all things being equal, hot water takes longer to cool down than cold water, and so it couldn't possible freeze faster. The winner speculated that hot water indeed freezes more quickly if the cold water is first supercooled. For decades, physicists have debated whether the. The mpemba effect is the name given to the observation that a liquid (typically water) which is initially hot can freeze faster than the same liquid.
