What is heat transfer by convection caused by?
Heat transfer during convection heating is simply caused by diffuse expansion through liquid with regard to the force of buoyancy. This phenomenon can be noticed in nature as well as forced in the lab
What is convection transfered through?
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
Convection only occurs in due to particles moving not just heat transfer as in conduction?
Yes, convection is the transfer of heat through bulk movement of a fluid, gas or liquid. The movement can be natural caused by density differences, or can be forced.
What is the definition of a convection?
convection is basically the up and down movement in gas and liquids caused by heat transfer.
What is the transfer of energy as heat caused by the collision of molecules?
When molecules collide and there is a transfer of energy as heat, this is called conduction. When fluids of different temperatures transfer energy by movement, this is called convection.

What is a great sentence for convection?
Convection is defined as the transfer of heat through a fluid,(liquid, or gas form) caused by motion of molecules. A pot of water on the stove, warms through the process of convection.
What is the definition of a Convection cell?
The transfer of heat through a fluid (liquid or gas) caused by molecular motion.
What does convection mean in science terms?
convection is the transfer of heat in a liquid or gas by thermal energy from one part of a fluid to another. ;0)

The heat transfer caused when heated liquids or gases rise is called?
convection
What are convection currents created by?
Convection currents are the flow of fluid (liquid or gas) caused by the molecular motion resulting from the transfer of heat through the fluid. In meteorology it is the vertical movement of atmospheric gases caused by heat, atmospheric pressure, condensation of water vapor, and other factors.
What form of heat transfer is caused by the greenhouse effect?
There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.
Where does convection happen?
Convection refers to the transfer of heat energy by the motion of a fluid such as air or water caused by differences in temperature within the fluid. Therefore convection happens wherever there is a fluid with a temperature gradient. This means that convection is happening continuously in the air around us and in bodies of water. A car heater and a convection oven are also considered to transfer heat by convection, but this is using the term liberally since the movement of the fluid (air) in these two cases is caused by a fan, not temperature gradient. So, while not perhaps being absolutely accurate examples of convection, still the heat is transferred through fluid motion.
What is the transfer of energy by heat caused by the collision of molecules?
When molecules collide and there is a transfer of energy as heat, this is called conduction. When fluids of different temperatures transfer energy by movement, this is called convection.
