Question

does the rate of mixing change with temperature? Why and how?

Answer 1

Yes because on increasing the temperature intercellular space between the particles of a matter increases which help in easy mixing.

Answer 2

Answer: If by mixing you mean Solution, then yes it does change.

Explanation: A solution is formed when the when the solute-solvent interactions overcome the inter-molecular forces between the solute molecules. When temperature is increased, the inter-molecular forces between the solute molecules become very weak, therefore, are very easy to overcome. Hence, the solution is formed much faster.
