WebConduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles ... WebOct 11, 2024 · The air touches the heat sink/radiator, and it picks up heat by conduction. 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

WebSo when hot water is placed beneath cold water, it will rise up while the cold water sinks down. This causes the mixing of the water you saw earlier. However, when the hot water … WebJul 10, 2014 · Convection. When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection. For this reason, "heat" and "hot air" tend to be confused with each other. WebMay 7, 2014 · See answer Advertisement Boeing7478i This is because its density increases. In a liquid, the density decreases, allowing it to stay on top of another substance. The liquid cools as it rises away from the core, and gets closer to the crust. The loss of temperature makes it more dense than the liquid. Welcome.
