Heating causes a bromthymol blue indicator solution to change yellow to blue rapidly why?

Bromthymol blue is an indicator solution that turns yellow in the presence of carbonic acid (H2Co3). Chemically, water and carbon dioxide combine to form carbonic acid. Heating the solution favors the dissociation of carbonic acid back to carbon dioxide and water and therefore the bromthymol blue returns to its less acidic state and back to it original blue color.

What is the process of rapid cooling of heated metal?
Quenching , or quench hardeningis the process of rapidly cooling hot metal in a cold liquid. Its a process in which iron alloys and steel are hardened. This is done by heating the material to a certain temperature, and then cooling it rapidly in a cold liquid, usually water.
Why do heated solvents dissolve solute faster?
One solvent is not faster than another, because different solutes require different solvents. If you are using the right solvent, the solute will usually dissolve rapidly. You can also make things dissolve faster by heating the solvent, and by stirring the solution.
