To prove: Diffusion becomes faster with the increase in temperature.

Activity:

i. Take a beaker A and beaker B.

ii. Pour hot water in beaker A and cold water in beaker B.

iii. Now, put a drop of ink in beaker A and beaker B.

Observations: We will observe that in beaker A, the ink spreads throughout the water faster than in the case of beaker B.

Conclusion: Hence, this activity proves that diffusion becomes faster with increase in temperature.
