Convection cells gizmos

The brand new Convection Cells Gizmo uses a sophisticated math model to generate simulated convection cells in a beaker of liquid held over a burner. Students can adjust the location and intensity of the heat source and the viscosity of the liquid. A second heat source can be added if desired as well.

I hope this helps you!!

Option (c) is the correct answer.

Explanation:

When we increase the concentration of a substance then it means we are increasing number of molecules of the substance. So, when there is increase in concentration of hydroxide ions the it means there are more number of ions into the solution.

Also, it is known that pOH =

Since there is increase in concentration so, this means that there will be decrease in the value of pOH.

Also,   pH + pOH = 14

so,                pH = 14 - pOH

                    pH = +ve

Thus, we can conclude that there will be increase in the value of pH.
