Question

give one simple activity/experiment to show rate of diffusion in liquid increases with rise in temperature

Answer 1

Take 2 beaker,some water ,potassium permagnate,one tripod stand,one burner Take one beaker with water and put a piece of potassium permagnate but do not stir or disturb it take another beaker and heat the water in it We can observe that in the first beaker the potassium permagnate(solute )took more time to dissolve whereas in the second beaker the solute diffused at greater speed This is because the heat which is applied increses the kinetic energy of the particles i.e the movement of particles increases and this helps to increase the rate of diffusion
