Example of Everyday applications with Convection

1. Car engines: Cooled by convection currents in the water pipes. Water is a very good substance to carry the unwanted heat away from the engine to the radiator.

2. The sun can cause very large convection currents of air. This flow of air is wind. In daytime, the land has a higher temperature than the sea. The warm air rises over the land and the coolair falls over the sea. So we feel a breeze from the sea.





3. Rising air over the land are convection currents and are used by glider pilots to keep their gliders in the sky.

4. Air conditioners are installed near the ceiling of the room, to allow the setting up of convection currents. The air-conditioner releases cool dry air into the room. As cool air is denser, it sinks. The warm air, being less dense, will rise. The air circulated and the temperature of the air will eventually fall to the desired value.


5.
Inversion layer. Air near ground is more dense than air higher up; no convection currents to lift pollutants.http://www.blogger.com/post-edit.g?blogID=8541793538969815640&postID=8144138354297716640

Hot room air is forced outside, while cooler air replaces it.
