The corners cool off faster because there are more opportunities for “heat beads” to fall out of the material there.
Although this is exactly what the diffusion equation predicts, actually doing the math by hand is difficult.
It seems as though a bunch of water is a good place to store heat energy, but the more time something spends being hot, the more energy it drains into everything around it.
Answer Gravy: This gravy is just to delve into why picturing heat flow in terms of the random motion of hypothetical particles is a good idea.
Call that something “k” and you’ve got the diffusion equation, .
The only reason to keep it on is so that you don’t have to wait for the water to warm up before you use it.Fan death is a well known superstition in Korean culture, where it is thought that running an electric fan in a closed room with unopened or no windows will prove fatal.Despite no concrete evidence to support the concept, belief in fan death persists to this day in Korea.The same equation describes the random motion of particles.If is either the density of “beads” or the probability of finding a bead at a particular place (if the movement of the beads is independent, then these two situations are interchangeable), then once again the diffusion equation describes how the bead density changes over time.
