Hey mate, here's ur answer:
When a gas jar, which is filled with air or is empty,is inverted over a gas jar containing bromine vapours the bromine vapours or molecules start to spread throughout the air filled jar as now they have a much bigger area to move.
This process is called DIFFUSION.
When the bromine vapours fill the second jar,v see that the colour of the pnce empty jar changes to brown as it is one of the properties of the bromine gas.
HOPE IT HELPS UH!

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.
