Pottasium Permanganate crystals put in hot water mixes faster than put in cold water why?

Open in App

Solution

Crystal crystallize out of the solution, when supersaturated solution is cooled. Cooling of solution leads to loss of energy. So, when heat the water in crystal is added, the lost heat is supplied to the crystal by hot water, and crystal dissolves.
