Eli5: Why can a thermal flask keep items cold for 24 hours, but only hot for 12 hours.
In: Physics
As many have already mentioned, heat transfer rates are directly tied to delta t, but there’s also another phenomenon that helps, the elusive and unexplainable mpemba effect. Hot water freezes faster than cold water. Sounds like it breaks physics to me, but damn if it hasn’t actually been proven thousands of times in cold climates
