WebThe air which is cold is released by the air-conditioners. Now, this cold air is denser than the warm air, and, hence, it sinks. The warm air, being less dense, rises and is drawn in by the air-conditioner. As a result, a convection current is set up and the room is cooled. 5. Radiator. Even the radiators work on the principle of convection. WebConvection currents can be seen in lava lamps. The wax inside the lamp warms up, becomes less dense than the liquid and so rises.

WebAtmospheric convection currents can be set up by local heating effects such as solar radiation (heating and rising) or contact with cold surface masses (cooling and sinking). Such convection currents primarily … WebA current is the steady flow of a fluid (such as air or water) within a larger body of that fluid. Large-scale currents are found throughout Earth's atmosphere and oceans. In the atmosphere, air currents are caused by the uneven heating of Earth's surface. In the ocean, water currents are caused by winds or differences in density.
