Why are thermos’s better at keeping things cold rather then keeping things hot ?
In: 4
The bigger the temperature difference between 2 objects, the faster the heat will flow between them and the temperature equalize. (Very sloppy phrasing, but it’s ELI5 right?)
There is not that big of a difference between “cold” and room temp, while the difference between “hot” and room temp is significantly larger. The difference between “hot” and room temp is roughly 3x or 4x larger than the difference between “cold” and room temp, thus thermoses will be able to keep something cold much longer than hot.
