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.
What else can I help you with?
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?
Diffusion describes the process by which particles in a gas spread out due to their random motion. The particles move from areas of higher concentration to areas of lower concentration, resulting in even distribution.
How could you measure the speed of diffusion in gases?
The gases will have to be converted into liquids so as to diffuse easily
Why rate of diffusion in liquid is slower than in gases?
The rate of diffusion in liquids is slower than in gases because the particles in liquids are closer together and have stronger intermolecular forces, which hinders their movement compared to gas particles. This results in a slower diffusion rate in liquids.
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 fastest in gas and slowest in solids?

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.

How does rate of diffusion of a gas in a liquid change on heating?
if the temp is higher then diffusion take place faster
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.
What effect will the number of particles and temperature have on the rate of diffusion of gas molecules?
An increase in the number of gas particles will lead to a higher rate of diffusion because there will be more particles available to move and spread out. Higher temperature will also increase the rate of diffusion as the particles will have more energy to move faster. Both factors contribute to more frequent and energetic collisions between gas molecules, promoting diffusion.
Which slavic country has the slowest rate of urbanization?
Moldova has the slowest rate of urbanization.
What measurements would need to be taken to calculate the rate of diffusion of a gas?
To calculate the rate of diffusion of a gas, you would need to measure the concentration gradient, which involves determining the concentration of the gas at two different points over a specific distance. Additionally, the temperature and pressure of the gas are important, as they influence the kinetic energy and behavior of gas molecules. Finally, the molecular weight of the gas is necessary, as it affects the diffusion rate according to Graham's law.
Is the diffusion rate in oxygen and bromine the same?
No, the diffusion rate of oxygen and bromine is not the same. Oxygen, being a smaller and lighter molecule, diffuses faster than bromine, which is larger and heavier. This is based on Graham's law of diffusion, which states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
Which pair of gas has same rate of diffusion at STP?
Hydrogen and helium have the same rate of diffusion at standard temperature and pressure (STP) due to their similar molecular weights and sizes.
