Question

what is necessary for a convection cell to be set up in a fluid? a. thermal gradient b. changes in density c. thermal gradient and changes in density

Answer 1

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 2

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
