In order for convection to happen, product with part temperature and also density has actually to circulation to a ar where the product there has a various 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)


In stimulate to create convection cells, the liquid must it is in of extremely high temperature and low density.

The lower component of the liquid when heated, the temperature increases significantly, as a result of which that expands. Due to this, that becomes much less dense, and tends to rise up in the direction of the surface. This rising fluid when get the surface, that is temperature at some point decreases. It then becomes denser and also subsequently sinks to the bottom. This is just how the cycle repeats, forming the convection cell in the fluid.

Thus, both the heat gradient and also density is responsible for the development of convection cells in a fluid.

Hence, the exactly answer is alternative (C).

The correct answer is C) heat gradient and also changes in density

What is essential for a convection cabinet to be set up in a liquid is thermal gradient and also changes in density.

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

The question is asking to choose among the following choices that says on what is crucial for a convection cabinet to be set up in fluid, basic on mine research, I would say that the answer would be letter C. Heat gradient and changes in density. I hope this would help


In the 1640s, the flemish chemist jan baptista van helmont carry out the classic experiment character below: ns filled a pot v 200 pounds of dust that had been dried in one oven. Then ns planted the stem that a pasture tree and also watered it v rainwater. At the beginning, the willow stem sweet 5 pounds. Because that 5 years, ns watered the tree with either rainwater or distilled water at any time it to be needed. The pot to be large, and also planted in the ground. I extended the pot through an steel plate. This had countless holes, which permitted water through however not dust. In this way, i can be assured that feasible dust accumulation over this 5 years did not significantly include to the weight of the dirt. ~ 5 years, the tree weighed 169 pounds, and around 3 ounces. Ns did no take right into account the load of the pipeline that fell each autumn. At length, i again dried the dirt, i beg your pardon weighed only 2 ounces much less than the early stage 200 pounds. I concluded the the 164 pounds that wood, bark, and roots, developed out that water only. In what means was valve helmont"s conclusion incorrect?
