What is the short definition of convection?
a process of heat transfer through a gas or liquid by bulk motion of hotter material into a cooler regionCompare conduction (def.
1) meteorol the process by which masses of relatively warm air are raised into the atmosphere, often cooling and forming clouds, with compensatory downward movements of cooler air..
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 is a sentence for convection?
Sentence Examples The nearly vertical vanes is balanced by the convection currents. Great irregular variations in radiation and convection sometimes produce a remarkably abrupt change of temperature at a certain depth in calm water. Gerdien’s estimate of the convection current is for fine weather conditions.
Is a fan an example of convection?
The hot air popper which is used to make popcorn also utilises the principle of convection. The hot air popper has a fan, vent, and a heating element. When the popper is turned on, the fan is employed to blow air on the heating element through the vent. The heating element, in turn, warms the air; which then rises.
What are 2 examples of conduction?
Everyday Examples of Heat or Thermal ConductionAfter a car is turned on, the engine becomes hot. … A radiator is a good example of conduction. … You can warm your back muscles with a heating pad.Roasting wieners over a campfire is fun until the heat from the fire is conducted up the coat hanger to your hand.More items…
What is the opposite of convection?
Convection is the transfer of heat by the actual movement of the warmed matter. … Conduction is the transfer of energy through matter from particle to particle. It is the transfer and distribution of heat energy from atom to atom within a substance.
What is the correct definition of convection?
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 is the process of convection?
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 currents within the earth move layers of magma, and convection in the ocean creates currents.
What are two different meanings for convention?
1 : an agreement between nations for regulation of matters affecting all of them. 2 : an agreement enforceable in law : contract. 3 : an assembly of persons met for a common purpose especially : a meeting of the delegates of a political party for the purpose of formulating a platform and selecting candidates for office.

What is a fact about convection?
convection, mode of heat transfer in fluids (liquids and gases). … Convection depends on the fact that, in general, fluids expand when heated and thus undergo a decrease in density (since a given volume of the fluid contains less matter at a higher temperature than at the original, lower temperature).
What is the opposite of conviction?
conviction. Antonyms: doubt, giving, disbelief. Synonyms: assurance, persuasion, belief.
What are some examples of convection?
Examples of ConvectionBoiling water – The heat passes from the burner into the pot, heating the water at the bottom. … Radiator – Puts warm air out at the top and draws in cooler air at the bottom.Steaming cup of hot tea – The steam is showing heat being transfered into the air.Ice melting – Heat moves to the ice from the air.More items…
What is convection used for?
Convection creates a dry atmosphere that caramelizes the sugars faster when roasting, so foods like meats and vegetables get browner, but the interiors stay moist. It saves energy: Because food cooks faster in a convection oven, and generally at a lower temperature, it’s a bit more energy efficient than a regular oven.
What is convection and how does it work?
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. … As a result, the particles take up more volume.
What do you mean by conduction?
the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts. transmission through a conductor.
