A Simple Experiment to Show How Cool Objects Can Keep Warm Objects Warmer Still:
- Roy, I am stunned by the “experiment” you plan to do: Everybody understands that the outside temperature affects the inside temperature of a house under constant inside heating. But it is an abuse of both physics and language to claim that a cold exterior is heating a warm inside, when the true physics is that the a warm inside is heating a cold exterior, that is that there is a uni-directional flow of heat energy from a warm inside to a cold outside, by conduction or radiation.
- I cannot understand from where you get such a strong urge to twist physics and language by claiming that a cold outside is heating a warm inside by “back conduction” or “back radiation” through the space separating inside from outside. Why do you insist propagating false physics which violates the 2nd law?
- Claes, you are the one abusing physics, and twisting my words. I never claimed that “a cold exterior is heating a warm inside”, only that it affects the temperature of the warm inside. Also, I never claimed there was such a thing as “back conduction”.
- I *do* however claim that the atmosphere emits IR radiation in all directions, and if the atmosphere emits IR downward it must then affect the surface temperature.
- Since you insist on twisting what I say, consider yourself banned along with the other Slayers I have banned.
PS1 If a question is met by an outburst of anger, the question may be a good one.
PS2 The idea put forward by Roy that "the atmosphere emits IR radiation in all directions...and it must then affect the surface temperature", is similar to phlogiston theory in the sense that some form of heat carrying particles (IR radiation/IR photons/phlogistons) are supposed to be emitted from the cold atmosphere, which "affect" the surface temperature by "keeping it warmer still". What drives Roy into this kind of ideas is a mystery to me. Evidently, Roy does not believe that heat conduction is carried out by some form of heat carrying particles/phlogistons transferring heat energy back and forth between different bodies, but for some reason believes that this is so in radiative heat transfer.
