Briefly explain why heating water close to boiling in a test tube would dramatically increase the rate of distribtution of dissolved particles, like KMno4, so that they distribute within the entire tube within several seconds? Please be specific in explanation. For animal physiology class. Solution It is due to the mechanism of convection. KMnO4 will distribute easily when water in the test tube is boiled, because heat transfer in a liquid occurs by the liquid movement itself. The liquid which is present at the bottom will get hot first and this will rise to the surface and the liquid from top reach the bottom, like this the liquid will move in a loop pattern (phenomenon called as convection) and this will allow the uniform distribution of water soluble particles present in that water..

Solution
It is due to the mechanism of convection.
KMnO4 will distribute easily when water in the test tube is boiled, because heat transfer in a
liquid occurs by the liquid movement itself. The liquid which is present at the bottom will get hot
first and this will rise to the surface and the liquid from top reach the bottom, like this the liquid
will move in a loop pattern (phenomenon called as convection) and this will allow the uniform
distribution of water soluble particles present in that water.
