Question

give an experiment to demonstrate diffusion

Answer 1

Object:

To demonstrate the phenomenon of diffusion.

Requirements:

Beaker, water, copper sulphate crystals.

Method:

Take a clean beaker and fill it completely with water. Place a big crystal of copper sulphate on one side of the beaker (Fig. 1).
Observations

After some time, crystal of copper sulphate disappears and its particles get equally distributed throughout the water.

Results:

Molecules of the copper sulphate move from the region of higher concentration, i.e., crystal, to the region of lower concentration, i.e., water, and thus show the phenomenon of diffusion
