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 the difference between conduction and convection?
In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles.
What is conduction in your own words?
Licensed from iStockPhoto. noun. The definition of conduction is the movement of something such as heat or electricity through a medium or passage. An example of conduction is using a metal rod to roast marshmallows on an open fire and feeling the heat rise through the rod from the fire to your hand.
What is conduction example?
Conduction of heat occurs when molecules increase in temperature; they vibrate, and this vibration and movement passes the heat energy to the surrounding molecules. Some examples of conduction of heat are accidentally touching a hot pot, or when a heating pad is applied to you directly and warms your muscles.
What does conduction mean?
1 : the act of conducting or conveying. 2a : transmission through or by means of a conductor also : the transfer of heat through matter by communication of kinetic energy from particle to particle with no net displacement of the particles — compare convection, radiation. b : conductivity.
What is the meaning of convection?
the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Meteorology. the vertical transport of atmospheric properties, especially upward (distinguished from advection). the act of conveying or transmitting.

What is convection give an example?
Everyday Examples of Convection Boiling water – The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. Radiator – Puts warm air out at the top and draws in cooler air at the bottom.
What are 4 examples of conduction?
Examples of 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 a synonym for conduction?
conduction, conductivity(noun) the transmission of heat or electricity or sound. Synonyms: conductivity.
What is another meaning of the word conductor?
conductor(noun) a substance that readily conducts e.g. electricity and heat. Synonyms: director, music director.
Is rubber a conductor?
The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.
