WebConvection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Convection in a liquid Convection in a liquid … WebConvection: Rising convection currents carry heat from the Sun’s interior to its surface, whereas cooler material sinks downward. Of course, nothing in a real star is as simple as diagrams in textbooks suggest. Stellar convection occurs as currents of hot gas flow up and down through the star (Figure 3). chiretsuWebDec 18, 2024 · The reason is that there is no gravity or “up and down, and thus no convection. The heat that the component or enclosure generates and is conveyed to the heat sink just lingers around that source and does not rise (“rise” has no meaning in a weightless environment). chi restaurant in bend oregon

Then, the hot air moves out of the way so that more cool air can take its place. The mechanism that moves the air can be convection (if it's a passive heat sink, or if I leave the ceiling fan switched off in my bedroom), or it can be forced by a fan. – Solomon Slow
