Question

When a gas jar containing air is inverted over a gas jar containing bromine vapour the reday bromine vapour diffuse into air. How does this happen

Answer 1

this is because bromine have high kinetic energy so they go up against gravity (in this case)and diffuse with air

Answer 2

Molecules of a gas has high kinetic energy and therefore, they tend to move rapidly from one place to another. Hence, gases has the ability to diffuse at a faster rate. As a result, bromine vapors diffuse into air due to their high kinetic energy.
