convection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy.

Mar 11, 2016 · Convection is important since it can affect the weather. The large masses of gases, liquids and solids can be moved via the circulating fluid of the convection current. The movement of tectonic plates on the earth’s crust occurs because of the convection currents.

Aug 31, 2023 · Through this article, we have explored ten astonishing facts about convection that highlight its significance and intriguing nature. From the mesmerizing patterns formed by convection currents to its impact on global climate systems, each fact unveils a unique aspect of this phenomenon.

Convection is single or multiphase fluid flow that occurs spontaneously through the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed.

Jan 19, 2025 · Convection is the transfer of heat through fluids (liquids or gases) caused by molecular motion. This process can be observed when boiling water, where hot water rises and cooler water sinks, creating a circular motion.

Nov 2, 2024 · Convection is the process of heat transfer within a fluid due to the movement of the fluid itself. When a part of the fluid becomes warmer, it typically becomes less dense and rises, while cooler, denser fluid sinks. This creates a flow that redistributes heat.

Jan 2, 2023 · Convection is the heat transfer process from one region to another due to the movement of fluids like air or water. The initial heat transfer occurs through conduction, but the primary transfer occurs through convection. It is the dominant form of heat transfer in liquids and gases. Types of Convection

What is Convection? Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to …

Oct 16, 2023 · Convection is the movement of heat because of the movement of warm matter. For example, atmospheric circulation moves warm air to cool places, causing wind . Wind, in turn, can enter and cool a room if the window is open.

Sep 18, 2022 · Conduction is heat transfer directly between neighboring atoms or molecules. Usually, it is heat transfer through a solid. For example, the metal handle of a pan on a stove becomes hot due to convection. Touching the hot pan conducts heat to your hand. Convection is heat transfer via the movement of a fluid, such as air or water.
