What is the thermal convection?
Thermal convection is a process by which the heat is transmitted using a heated object. This is most often seen in liquids and gas and can be easily demonstrated by air as an example. The thermal convection is one of the main ways of moving heat, while the line and radiation are also common methods of transport of heat. There is simply more heat or less heat. The thermal convection is therefore not just about moving hot objects. It is about the way the temperature as a whole tries to alleviate itself, either to its surroundings or to objects that cause it to warm up. The movement of warmer and colder gases and liquids causes overall moderation, although it is never possible to achieve perfect balance. When the door opens, the hot air rush immediately shoots from the oven. If it is to place a small flag on the oven base, the flag should wave towards the oven, as the cold air fills, as the hot air rises. When the cooling air is heated, it also rises.
The air that rises is pushing the radiator air above it, often forcing it to the side and finally down. This air will remain on this lower level until it is heated again and begins to rise again. This thermal flow process is repeated until the heat source is neutralized and the temperature throughout the area is consistent. If this does not happen, the process will continue for an indefinite period.
The process is also visible in the water and is not always useful. For example, if the surface of the lake quickly cools down, the water under the warmer push up. With this increasing, dead matter, such as algae, which slowly decomposed on the bottom of the lake. Being exposed to air and Sunlight, the crumbling mass increases its decomposition rate and could starve oxygen from the lake. In this example, the thermal convection is responsible in the indirect way of great damage to the living ecosystem.
Despite the previous example, thermal convection is usually considered fromAnd a useful phenomenon. Most furnaces and furnaces run on the principles associated with thermal convection, so the lives of most people are more comfortable. Also, moderating the temperature in the ecosystem is also often very useful for life forms that live in the system. The thermal convection is also one of the main driving forces in the weather.
