Explanation:

The gas jar(A) containing a colorless gas is kept upside down over another gas jar, containing a reddish- brown gas . The two jars are separated by a glass plate placed in between the jars.

1. The above set up is actually an experiment to demonstrate the phenomenon of diffusion. Jar A contains normal air and jar B contains the colored bromine vapor. When the glass plate between both jars is removed, both the gases acquire the reddish-brown color after some time.
2. Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.
