| Nov 18, 2021 at 8:17 | comment | added | Ishaan Manish | Does this answer your question? Is rising air high pressure or low pressure? | |

| Nov 14, 2021 at 17:35 | comment | added | Roger V. | @Markoul11 think of how pressure is calculated in statistical mechanics - it has nothing to do with intermolecular collisions, which are rare in gas (as opposed to a liquid). | |

| Nov 14, 2021 at 16:54 | comment | added | Alchimista | A question: isn't convection a form of buoyancy anyway? | |
| Nov 14, 2021 at 16:36 | comment | added | Markoul11 | "but the collisions between the molecules seem too rare to talk about pressure." How you've came to this conclusion? Seems to me that the higher kinetic energy hot air molecules displacing cooler air molecules being the central mechanism behind the buoyancy phenomenon and actual reason why hot air rises up for a normal atmosphere pressure gradient of one At at sea level. | |
