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. Convection in a gas Air current close to a radiator Air... WebApr 23, 2024 · Convection currents rely on the constant cyclical motion of air, water and other substances to distribute heat. As heated air rises, for example, it pulls cooler air into its place -- where it can be heated, rise, and pull in more cool air.
