Some brilliant bits in this thread in the last few days!
Of course it does you pedantic bellend! At least in any system that contains a gas and a gravitational field, (which is nearly all of them). Don't bring your niche physics cases to a c+h thread, you utter harpy.
Without turning this thread into a Junior School Physics lesson, I was always told that it was cold air that falls and pushes the warm air upwards.SpeedMattersNot said:

But...heat doesn't rise.

A hot gas or liquid will be less dense than the same gas at a lower temperature. So if you warm a bubble of gas, the denser (heavier) cooler gas will fall down and displace the bubble. The bubble of heated gas will rise as it is forced out of the way by the cooler gas.
A heated gas or fluid will rise in a mass of similar but cooler gas or fluid.
But heat itself does not rise. Consider a sphere of metal in a vacuum, heated from the centre. Would it be cooler at the top or the bottom, or would it have an even surface temperature?

If you're going to be pedantic then you should probably steer clear of absolute statements.A hot gas or liquid will be less dense than the same gas at a lower temperature.

Heat does rise. But only as a result of cooler substance falling.
Just out of curiosity. Not saying the above is false - but how does one prove that heat rises as a result of cooler substance falling, rather than the heat rising and displacing the cooler substance?

No, the heated substance rises. The temperature rise within a fixed heated body (one that doesn't move), with equal cooling on all surfaces would not be affected by gravity. That is to say, that heated body would have the same temperature at the top as at the bottom. It's really not difficult to comprehend.mikeveal said:

Moving on to brighter and better things, my little lunchtime guilty pleasure of C&H shorts has now been exposed due to uncontrollable laughter as a result of this....
