Question

What do you observe when a gas jar which appears empty is inverted over gas jar containing Bromine vapours. Name the phenomenon and define it

Answer 1

As we know gases are in free state and are moving in rapid motion inside the container. Same happens when air jar will be inverted to bromine vapour jar, the particles of air and bromine vapour will colloid each each other and get mixed with each other. This process is called Diffusion.
