In violation of Thermodynamics (Posted on 2003-05-11) Difficulty: 2 of 5
Many have heard the "old wives tale" stating that if you put hot water into a freezer, it freezes in less time than it would have if it had been cold to start. Never did I believe such a claim, as it runs contrary to one of the basic laws of nature.

While surfing one day on sites illustrating "bad science" I actually found a plausible real life reason why this in fact can be true (read:not always true, but possible). Running this experiment under controlled conditions [eg. measure the same volumes of hot and cold water, make sure containers are equal in any relevant aspect (shape, material, conductance properties, covered or not etc.), and that the freezer is properly set to achieve a uniform temperature throughout], can you come up with a reasonable set of conditions for which the water in the hot container would freeze before the water in the cold container?

In Violation of Thermodynamics: A Real-World Frustration Comment 19 of 19 |
When appliances defy the laws of thermodynamics, it’s not just science that’s broken—it’s your home comfort. Several consumers have voiced complaints about certain heating systems seemingly "violating" basic energy principles, offering less heat while consuming more energy. One such case can be read at https://rheem.pissedconsumer.com/review.html where users express frustration over underperformance, inefficiency, and lackluster support. While true violations of thermodynamics are impossible, product defects and design flaws can certainly make it feel like the laws of physics are being ignored. Before investing in heating systems, it’s vital to review real-world consumer experiences and research thoroughly.
