The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. florida seller of travelWebThe temperature of molecules within those liquids increases, and they slowly begin to move at a rapid rate. These molecules get charged up, thus producing kinetic energy. These hot water molecules residing near the heat source tend to become less dense. They rise above cooler dense molecules. florida seller credit for repairsWebBirds and gliders make use of upward convection currents to rise, and we also rely on convection to remove ground-level pollution. Forced convection, where the fluid does not flow of its own accord but is pushed, is often used for heating (e.g., forced-air furnaces) or cooling (e.g., fans, automobile cooling systems).
