Quick Answer: What Word Does Convection Come From?

What is the associated word of convection?

In this page you can discover 13 synonyms, antonyms, idiomatic expressions, and related words for convection, like: boundary layer, advection, upwelling, turbulence, oscillation, , radiative, convecting, magnetic field, flux and evaporation..

Is convection a word?

Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather.

What is an example of the word convection?

boiling water – When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion. radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom.

What is needed for convection?

Natural convection, or free convection, occurs due to temperature differences which affect the density, and thus relative buoyancy, of the fluid. Heavier (denser) components will fall, while lighter (less dense) components rise, leading to bulk fluid movement.

What’s the opposite of convection?

What is the opposite word for Convection? hold. convection and hold. keeping.

What is a fact about convection?

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.

What are the applications of convection?

Application of Convection CurrentsHousehold ventilation can make our house cool. The air which we breathe out is warmer and lighter. … In a domestic water heater, water is heated in the boiler by a gas burner or heating coil. … An air conditioner also uses convection currents to cool a room.Jun 10, 2020

What is convection in simple words?

1 : the action or process of conveying. 2a : movement in a gas or liquid in which the warmer parts move up and the cooler parts move down convection currents.

What are three types of convection?

Types of ConvectionNatural convection.Forced convection.

What causes convection?

Convection occurs through the movement of particles. As particles become heated, the molecules move faster and faster, and as molecules move apart, density decreases. The warmer, less dense material rises compared to the surrounding cooler, higher density material.

What are 4 examples of conduction?

Conduction: Touching a stove and being burned. Ice cooling down your hand. Boiling water by thrusting a red-hot piece of iron into it.

What is convection and why is it important?

Convection currents play a role in the circulation of fluids. Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. … Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.

What are non convection examples?

Non Example: The heat is transferred to the burger without direct contact. Why is this not an example of convection? through a fluid (gas or liquid).

What are 4 examples of convection?

Convection comes into play while boiling water. … Blood Circulation in Warm-Blooded Mammals. … Air-Conditioner. … Radiator. … Refrigerator. … Hot Air Popper. … Hot Air Balloon.More items…

What is difference between conduction and convection?

Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.

What is convection and how does it work?

Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles.

What is convection flow?

Convective transport (convective flow, bulk flow, convection) may refer to either heat or mass transfer. … In the context of membranes, convective flow refers to the transport of fluid (pure solvent or solution) across a porous mem- brane, which is driven by the applied pressure.

Where does convection occur?

mantleConvection currents in the Earth occur in the mantle. The core of the Earth is extremely hot, and material in the mantle close to the core is heated…

Is boiling water an example of convection?

The hot water molecules become less dense, and they rise above the denser cooler molecules. This movement of molecules creates convection currents. Boiling water is an example of forced convection.
