Question

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

Answer 1

Hint : Diffusion is the process that is engaged in this circumstance, and diffusion will be measured in terms of kinetic energy. Bromine has an extremely high kinetic energy as compared to air. The heavier ingredient will sink to the bottom, while the lighter element will ascend to the top.

Complete Step By Step Answer:
Diffusion is defined as the migration of a chemical from a high-concentration area to a low-concentration area. Diffusion occurs in liquids and gases when particles migrate randomly from one location to another. Diffusion is the mechanism through which chemicals flow into and out of cells in living things.
Bromine is an atomic number $35$ chemical element with the symbol$Br$. It's the third-lightest halogen, and at room temperature, it's a seething red-brown liquid that quickly evaporates to form a similar-colored vapour. It has characteristics that are halfway between chlorine and iodine.
When a gas jar full of reddish brown bromine vapours is inverted over a gas jar full of air. It was noticed that the reddish brown bromine vapours expanded out into the upper jar after a while. Diffusion is the term for this type of mixing. In gases, diffusion is the fastest, whereas in solids, it is the slowest. It rises in response to a rise in temperature.

Note :
Bromine has an extremely high kinetic energy when compared to air, therefore it prefers to rise and mix with it. Because bromine is heavier than air, it will settle at the bottom of the jar while air rises to the top. After the impact of particles, the entire jar will appear reddish-brown due to particle diffusion.
