How does cold transfer if it’s just the absence of heat?
In: Physics
Cold do not travel as it is not a thing. It is heat that travel in the other direction. It is heat that travel from the warmer object to the colder object. The result that the warmer object the a colder and the colder object get warmer.
The transfer is exact the same as when heat is transferred. There is not fundamental difference between when it is warmer outside and it hear up a house compared to when it is colder outside and it cool down your house.
There is a practical difference and that is that you can generate heat by burning fuel or using electricity. Covering heat to other energy is a lot harder hand you need a temperature difference to do that. So it is a lot easier to warm stuff upp then to cool then down.
