Question

Describe an activity to show taht diffusion increases with an increase in temperature

Answer 1

In order to prove this statement, one can perform the following activity-

Take two beakers, one consisting of cold water and another consisting of hotwater. Now let the beaker with hot water be beaker A and another be B. Put red ink in each of the beakers. Observe both the beakers carefully.

Observation- It will be observed that in beaker A the ink spreads throughout the water faster than in the case of beaker B.

Conclusion- Therefore this activity shows that diffusion becomes faster with increase in temperature but is slow when there is decrease in temperature.
