Question

Give an experiment which show that rate of diffusion in liquids increase with rise in temperature

Answer 1

First take cold water than try to mix sugar in it .It is not easy .But if you take warm water it can easily diffused .The conclusion is that kinetic energy is directly proportional to temperature .

Answer 2

Answer: Take two beakers fill one beaker with hot water and the other beaker with cold water.Now add one crystal of potassium permanganate to each beaker. Now take a loke at the beakers you will notice that the beaker with hot water has almost compleatly dissolved the cystal and has turned to purple colour completely with out stiring it but in the beaker with cold water there only a few streaks of purple and you can see the cystal lying on the bottom of the beaker.  

Explanation: This happens because,particles of matter are continuously  moving, that is, they possess what we call  the kinetic energy. As the temperature rises,  particles move faster. So, we can say that with  increase in temperature the kinetic energy of  the particles also increases.
