Question

When a gas jar containing air is inverted over a gas jar containing bromine vapour , the red brown bromine vapour diffuse into air .Explain how bromine vapour diffuse into air.

Answer 1

Br is in gaseous state and all gases have property to flow randomly in each direction with out any restrictions
So Br particles move and diffuse to next jar

Answer 2

Explanation:

In gases, we know that particles are held by weak Vander waal forces. As a result, they have more kinetic energy and thus, more number of collisions take place between its molecules.

Therefore, molecules of a gas move rapidly and randomly from their initial place. That is why, they tend to diffuse at a rapid rate.

Hence, when a gas jar containing air is inverted over a gas jar containing bromine vapor , then the red brown bromine vapor diffuse into air as the gas molecules have weak intermolecular forces.

Thus, bromine gas diffuses into air.
