Mostly what I learnt during physics. Yup. That sums up my physics from college.... Chara Thea ' you' re THEE MCI DYNAMICS letting the cold L. -Ifhe hag? gags um thermodynamics physics tags are cool

Cue the comment section full of people reciting their Professors and textbooks accompanied by pictures of Bill Nye the Science Guy.

What wrong with citing professors and textbooks? More accurate information to me.

A cool mass of air from outside the window pushes the less dense higher temperature air up and impacts you.

What is the absence of heat sir?

iv'e seen so many variations of this pic....

why did batman really slap robin in that pic?
User avatar #73 to #45 - confetti (12/01/2012) [-]
Batman thinks that, when Superman was young, he killed his dad. So he wants revenge, but Robin overhears him and tells him it goes against everything Batman taught Robin about justice. Then Batman slaps him.

I don't give a **** how it gets cold, it's ******* cold.

When you have the window open, unless there is 0 pressure difference between the room and the outside, and no wind blowing, the heat isn't going to transfer through the air much. Rather, in most normal circumstances the air itself will move. Usually in through the window into the room. So, you aren't letting the cold in, you're letting the cold air in.

Why is he getting negative thumbs?
I'm pretty sure he's right.
There's a reason you feel the cold air hit you. The air isn't simply transferring heat. It doesn't work like that. Instead, hot air goes over, cold air goes under, one goes in, the other goes out.
User avatar #21 to #18 - Lambda (12/01/2012) [-]
Well, the air does transfer heat. But that effect is pretty slight, what you're actually feeling is the cold air moving.
And yes indeed, hot air rises and cold air sinks. If you've ever opened an outside door in the wintertime, you know your feet will feel the cold first.
User avatar #39 to #21 - coolcalx (12/01/2012) [-]
the air moves due to convection transfer, and you feel the cold air due to conduction transfer with it. the reason you FEEL the cold is because the heat energy in your molecules is being transferred to the air, causing you to feel a negative temperature flux aka "cold"

I learned that in middle school.

Cold is an absence of heat. It moves in as heat moves out. It's the same process, just described with different words.
User avatar #15 to #9 - coolcalx (12/01/2012) [-]
no, when something is "cold" it has less energy than something that is "hot." heat is energy.
in order for something to become hotter, you have to add heat (energy) to it. in order for something to be come colder, you have to remove heat (energy) from it.
heat moves, cold doesn't.

I thought cold air pushed away hot air, it's not that hot air rises, it just gets pushed up and out by colder air.
#75 to #69 - punkrockdude (12/01/2012) [-]
While the air does technically do that, thermodynamics states that there is no such thing "cold (energy)", only lack of heat
User avatar #77 to #75 - commontroll (12/01/2012) [-]
Yes, but the cold air (AKA, the air lacking in heat in comparison to the air around you) would then be entering into the room. Thus, cold air (air colder than the air around you) is indeed entering. Cold is just a comparison.
