WebAug 26, 2024 · Convection works when a liquid or gas is unevenly heated. Hot liquids (and gases) are less dense and rise, causing. The warmer section of the material will rise while the cooler part sinks. This creates a current of warmer material going up and a current of cooler material going down. Why do convection currents rise in air? Two types of convective heat transfer may be distinguished: • Free or natural convection: when fluid motion is caused by buoyancy forces that result from the density variations due to variations of thermal ±temperature in the fluid. In the absence of an internal source, when the fluid is in contact with a hot surface, its molecules separate and scatter, causing the fluid to be less d… WebJul 12, 2024 · Meaning: Transmission of heat energy through liquid or gaseous medium by warmer material moving into a cooler location, is called convection. In this article, students will learn about what is convection and shall look at some common examples of this phenomenon. ... (sink).
