Thinking of cold penetrating/moving is a terrible mental model. First it is physically wrong. Second the more physically correct mental model of heat moving is just as conceptually easy. Third once you start thinking of heat energy moving classical thermodynamics becomes quite a lot simpler to understand.
I'm not sure about the best mental model for electric circuits. I never understood electricity.
- BlueTemplar 6y agoFunny how it's a parallel to electric current having the "wrong" sign...
- gvjddbnvdrbv 6y agoNot always. In an ionic fluid electric current can be transmitted via movement of positive ions.
- beervirus 6y agoEverything you just said applies equally well to conventional current. What kind of situation is there in which thinking about cold propagating instead of heat will give the wrong physical intuition?
- gvjddbnvdrbv 6y agoMaybe that's why I never understood electricity if the mental model they teach is just physically wrong... The OP is an example when they talk about cold penentrating which makes no sense.
