Gas molecule always move. The movement is called Brownian Motion, a random behaviour of molecule and atom in fluid state. These little motion enhance diffusion even without any additional driving force. Gas had less interaction force than liquid and so the speed of motion is a lot greater and so higher diffusivity.

∙ 7y agoThe less dense a gas is the faster it diffuses. Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass. For some common gases, the order of rate of diffusion from the slowest is chlorine, carbon dioxide, oxygen, nitrogen, helium and hydrogen.

Why is diffusion slowest in solids and fastest in gas?
Maybe its the slowest in solids because the particles on it is compressed or tightly squeezed.While in gas, they are the fastest because the particles moves freely because gas is the most spacious matter of the 4.
Name for the particles in a gas spreading out?
When the molecules of a gas spread throughout another medium, the process is called diffusion. The rate of diffusion can be influenced by temperature and pressure.
What happens to rate of diffusion on heating?
On heating the rate of Diffusion increases..
As partial pressure increases what happens to the rate of diffusion?
Rate of diffusion will increase.
Theory of gas diffusion coefficient of acetone using winkelmann method?
The theory of gas diffusion coefficient of acetone using the winkelmann method is to diffuse the gas into a volatile liquid. This can be done by confining the liquid in a small narrow tube and observing the rate of evaporation.
Does hydrogen gas have a low rate of diffusion?
No, it is the lightest gas of the universe so has the highest rate of diffusion.
Which of the carbon monoxide sulfur dioxide nitrogen dioxide and ozone diffuse at the slowest rate?
According to Graham's Law, diffusion rate of a gas is inversely proportional to the square root of the molar mass of that gas. Put another way, the heavier the gas, the slower it will diffuse. CO is 28; SO2 is 64; NO2 is 46; O3 is 48. So the slowest to diffuse would be SO2.
Why diffusion is maximum in gases?
rate of diffusion is inversely proposnal to density, density of gas is less. so diffusion rate is high
Why diffusion is fastest in gas and slowest in solids?
Maybe its the slowest in solids because the particles on it is compressed or tightly squeezed.While in gas, they are the fastest because the particles moves freely because gas is the most spacious matter of the 4.

What is the difference between an oil and gas well test?
The difference is that,an oil is a dark viscous liquid with high density and low rate of diffusion why gas is a well pronounce substance with low density and rate of diffusion.

What is the definition of Graham's law of diffusion?
This law relates the rate at which a gas diffuses or effuses to the type of molecule in the gas. This rate of diffusion of a gas is inversely proportional to the square root of it's molecular mass.

How does rate of diffusion of a gas in a liquid change on heating?
if the temp is higher then diffusion take place faster
Which slavic country has the slowest rate of urbanization?
Moldova has the slowest rate of urbanization.
