In convection why does cooler material sink

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). WebSep 20, 2012 · Why does cool material sink when convection takes place in the mantle? Cool things always sink (because they are more dense) and hot things always rise …

WebDec 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). WebThe heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, hot fluids tend to rise, whereas cold fluids … ray white werris creek https://procus-ltd.com
