Question

Explain why, diffusion occurs more quickly in a gas than in a liquid?

Answer 1

Hint: Diffusion is the net migration of anything from a higher concentration area to a lower concentration area (e.g., electrons, ions, molecules). A difference of gradient in concentration contributes to diffusion.

Step-By-Step answer:
A gradient is a variation in the magnitude of a variable, e.g. the concentration, pressure, or temperature, typically with a difference in the distance. A distance shift is referred to as a gradient in energy, a distance increase of pressure is called a pressure gradient, and a distance shift is called a temperature gradient.
The molecules of gas have more kinetic energy than liquid molecules and are smaller. Fluid diffusion is slower because the particles move slower in a fluid. When the temperature is changed, it occurs quicker. Liquid provides less room to move so that collisions between the molecules are more frequent and the diffusion rate is slower. For gases there is more space. As a consequence, less collisions are creating an improved diffusion rate between molecules.
The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly. Therefore, diffusion of gases is much quicker than liquid diffusion. The truth is that gas particles are about ten times heavier in gases than liquids at comparable temperatures, so the average density of the particles is far greater.

Note: The notion of diffusion is widely employed in various areas, including physics (particle diffusion), chemistry and so on. Nevertheless, both of which represent the main concept of diffusion, which occurs from a stage or location where the substance (e. g. particle, idea, etc.) is at a large concentration.
