Shut the window you're letting in the cold

To which i replied 2nd law of thermodynamics, the heat is getting out.

[amcdonald]

Surely the second law of thermodynamics, is that you don't talk about thermodynamics

[Spacecadet]

I presume you didn't do physics beyond GCSE

Warm air OUT
Cold air IN

If that's what GCSE physics taught you I'm glad I din't 'do it' either!!!

Better to be correct on the obvious than ignorant on the advanced.

It is an awful long time since I did physics or thermodynamics but aren't the laws of thermodynamics concerned about closed or isolated systems?

So heat doesn't get "in" or "out".

Cold is lack of heat. If heat is going out then cold is going in.

Presumably if you open a window in totally still air then you get convection. Hot air flowing out of the top of the window will be matched by an equal volume flowing in at the bottom.

[scooterscot]

Cold is lack of heat.

I suppose if asked what is light you'd tell me it's not dark.

[Old Greg]

I suppose if asked what is light you'd tell me it's not dark.

The correct parallel is that dark is lack of light.
