gases have the fastest diffusion and Brownian motion give reason
Dear student,
Gases have the fastest diffusion because the particles are loosely packed due to which they can move freely, so the rate of diffusion is faster in the air. Their particles have the maximum kinetic energy.
Brownian motion (or Brownian movement) is defined as the continuous and random motion of the particles suspended in a liquid or in a gas. It is caused by the collision of these particles with each other and with the molecules of the surrounding medium due to their random movement with varying velocities. It was discovered by Robert Brown in the year in 1927. He observed that pollen grains when placed in water are not at rest but move continuously in a zigzag manner. He termed this motion as Brownian motion.
Brownian motion is maximum in gases because of the higher kinetic energy of the gaseous particles.
Regards
