The movement of matter due to differences in density and the transfer of energy that results from this movement is called?
convection current
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.
Is it true that heat transfer by the movement of currents within a fluid is called density?
No, it is not true that heat transfer by the movement of currents within a fluid is called density; it is actually called convection. Density is something else entirely, it refers to weight per a given volume. Of course, density is relevant to convection. Heat causes fluids to expand and therefore to become less dense, and therefore to rise.
Convection occurs when a warm liquid or gas?
Convection occurs when a warm liquid or gas moves moves into a region where the surrounding liquid or gas is a different temperature. An example of this is a warm gas rising into a region where the surrounding gas is cooler due to the lower density of the warm gas. Movement of gases and liquid due to differences in density (because of differences in temperature) is referred to as "natural convection". When the movement is caused by another force such as a pump or a fan or a mixing blade, then it is termed "forced convection".
What causes the transfer of thermal energy during convection?
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
What is a good sentence for convection?

How is density involved in convection?
In convection less molecules occupy large volume as in air to reduce the density.

How is convection related to density?
It is related by the grams that are measured by density
The movement of heat through a liquid or gas is called what?
heat moves through liquid by convection. Cold liquid with a higher density is pulled to the bottom of a pot by gravity forcing hot water to the top. As it does this they mix and the cold water is warmed by the hot water.
Is temperature the only factor that drives convection?
No Density also drives convection.
What is the transfer of energy that occurs due to density differences in the air?
Convection.
Differences in a material's is what drives convection?
Differences in a materials __________ is what drives convection
