Question

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

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.

• The rate of diffusion is the fastest in gases and the slowest in solids.

• Bromine gas is heavier than air, so it would settle in low-lying areas.

• Gases has the ability to diffuse at a faster rate. As a result, bromine vapors diffuse into air due to their high kinetic energy.

• Diffusion is the process in which mixing of substances with another substance takes place due to motion of particles.
