Question

When a gas jar containing air is inverted over a gas jar containing bromine vapour diffuse into air. Explain how bromine vapore diffuse into air.

Answer 1

Answer:

When a gas jar full of bromine vapours (reddish brown) is inverted over a gas jar containing air over it. It is observed that after sometime, the reddish brown vapours of bromine also spread out into the upper jar. This mixing is called diffusion. The rate of diffusion is the fastest in gases and the slowest in solids. It increases with an increase in temperature.

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.
