I am giving an example here...you can relate to it and write an activity or experiment.

here we go.....

take a cup of cold water(chilled) and put some sugar crystals in it and with the help of stirrer try to mix the mixture.

now take a cup of hot water(same volume as taken above) and now put sugar crystals and try to mix them together.

what do u observe?...


exactly when the temperature of water is higher the sugar crystals mix with water in no time as opposed to the cold water.

this give us an idea that when the temperature of liquids increases the property of disffusion becomes more prominent.


hope u get it

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.
