| Oct 31, 2015 at 22:32 | comment | added | Gert | @hyportnex: can you show me an example of what you mean here? | |
| Oct 31, 2015 at 22:21 | comment | added | hyportnex | You wrote "When heat flows from hot to cold, molecular kinetic energy is transferred from the hotter to the colder area. This can obviously not happen in the reverse direction." but this is true only if there are no other forces ("gradients") present. | |
