प्रश्न

Bromine and air take about 15 minutes to diffuse completely but bromine diffuses into a vacuum very rapidly. Why is this so?

टिप्पणी लिखिए

उत्तर

Bromine diffuses slowly in air because the motion of bromine particles is obstructed due to the collision with the moving air particles. But bromine diffuses very rapidly in vacuum because in vacuum there is no gas, and the motion of the particles of bromine gas is not obstructed by any other particle. Therefore, the diffusion rate in vacuum is high.
