I recently learned that hot water can freeze faster than cold water. Perhaps you already knew this but it was news to me. It’s a phenomenon known as the Mpemba Effect. This Mpemba Effect seems counterintuitive. Water freezes at 32 degrees. Since cold water is closer to 32 degrees than hot water, most would assume that cold water freezes first. Yet it has been studied extensively by scientists and experiments have shown hot water can freeze first. This isn’t true 100% of the time, but it does happen when the conditions are right. There are a number of theories about… Read More
I recently learned that hot water can freeze faster than cold water. Perhaps you already knew this but it was news to me. It’s a phenomenon known as the Mpemba Effect. This Mpemba Effect seems counterintuitive. Water freezes at 32 degrees. Since cold water is closer to 32 degrees than hot water, most would assume that cold water freezes first. Yet it has been studied extensively by scientists and experiments have shown hot water can freeze first. This isn’t true 100% of the time, but it does happen when the conditions are right. There are a number of theories about why this occurs. The leading explanation is that hot water evaporates more than cold water, leaving less water to freeze. It could also be due to convection currents, which are stronger in warmer water, allowing for ice crystals to spread faster. Others believe it may be related to the chemical structure of water. In all likelihood, it is the interplay of various factors. #-ad_banner-# You might be asking what this has to do with investing. To me, the Mpemba Effect illustrates that logic alone may not be enough to find the right answer. You have to dig… Read More
