In order for convection to happen, material with some temperature and density has to FLOW to a place where the material there has a different temperature and density.

You are watching: What is necessary for a convection cell to be set up in a fluid

Material doesn"t FLOW in solids, only in FLuids.



Option (C)

Explanation:

In order to generate convection cells, the fluid must be of extremely high temperature and low density.

The lower part of the fluid when heated, the temperature increases significantly, as a result of which it expands. Due to this, it becomes less dense, and tends to rise up towards the surface. This rising fluid when reaches the surface, its temperature eventually decreases. It then becomes denser and subsequently sinks to the bottom. This is how the cycle repeats, forming the convection cells in the fluid.

Thus, both the thermal gradient as well as density is responsible for the formation of convection cells in a fluid.

Hence, the correct answer is option (C).



Answer from: tinasidell1972

The correct answer is C) thermal gradient and changes in density

What is necessary for a convection cell to be set up in a fluid is thermal gradient and changes in density.

We are referring to fluid dynamics. A convection cell is present when a fluid is warmed and loses density. When density difference exits within a body of gas or liquid, we are talking about a convection cell. This is a cycle that repeats and it forms a pattern of motion. The blowing of the wind is a by-product of convection cells in the atmosphere.



Answer from: bowtie123
The question is asking to choose among the following choices that states on what is necessary for a convection cell to be set up in fluid, base on my research, I would say that the answer would be letter C. Thermal gradient and changes in density. I hope this would help
