Diffusion in Gas

Diffusion in Gas

(Diffusion in Gas)
Observation
The brown colour bromine vapour spreads evenly throughout the gas jar in a few minutes
  • Bromine vapour is made of tiny and discrete molecules that move randomly to fill up space.
  • Bromine vapour moves randomly and diffuses in all directions in air from areas of higher concentration to areas of lower concentration.
Conclusion : The rate of diffusion is highest in gas and lowest in solid.
