Convection is caused by temperature differences, in a gas such as air, which affect the gas density in local areas thus causing movement of the gas, generally upward due to buoyancy of warmer gas compared to the average density. Thus heat from a heating element near the floor of a room can be spread through the room without any forced circulation.

∙ 12y agoconvection as you know is one of the three ways in which heat is transferred, the other two are conduction and radiation. there are two types of convection heat transfer, one being free convection which is ambient air molecules which are in contact with each other which transfer heat to neighboring molecules. The other type of convection is forced convection where the heat transfer is not allowed to occur ambiently, rather it is made to occur faster with the use of a mechanical device.

The word used to describe the cycle of hot and cold gas?
convection
Describe how energy flows between hotter and cooler objects?
from radiation and 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.
Which transfer of energy occurs mainly through the process of convection?
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
Which process causes the transfer of energy by air currents within the Earth's atmosphere?
convection
Conduction convection and radiation are describing what process?
In simple terms, conduction, convection and radiation describe the three modes involved in the transformation of heat energy from one place to another.
What are the correct order of the steps which describe the convection process in the mantle?
You'll find the rather complete answer in the Related Link below
How can convection be transferred?
You don't transfer convection. Rather, convection is a process whereby heat energy is transferred.
Describe a convection in a room heated by a radiator?
it hotter
Heat is transferred by the movement of currents within a fluid by a process called what?
convection
The process by which hot and cold air are transferred in the atmosphere is?
I think it is tides or upwelling?
What energy process fuels the sun?
convection
What is the process of transferring thermal energy?
convection
Describe how radiation.conductionconvection heat up atmosphere?
describe how radiation,conduction,and convection heat up atmosphere?
What is what is convection?
In this process, heat is transferred by the bodily movement of particles of the medium due to difference in densities of different parts of the medium. convection process is also slow.
What is convection answer?
In this process, heat is transferred by the bodily movement of particles of the medium due to difference in densities of different parts of the medium. convection process is also slow.
The movement of molecules from high concentration to low concetration?
Well there are several terms to describe that process depending on the circumstances. These terms include osmosis, diffusion, convection and advection
