Does diffusion take place in air?
How does diffusion happen? Diffusion occurs in gases like air and liquids like water because their particles can move around and collide with each other randomly. For example, if you mix two drinks, the liquids diffuse into each other.
Why diffusion of bromine is faster in vacuum than in air?
Bromine diffuses slowly in the air because the motion of bromine particles is obstructed due to the collision with the moving air particles. But bromine diffuses very rapidly in a vacuum because in a vacuum there is no gas, and the motion of the particles of bromine gas is not obstructed by any other particle.
Where does the diffusion process take place?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
Why does gases diffuse faster in vacuum than in air?
Diffusion is the random movement of particles.In the diffusion process of bromine and air,the bromine particles continuously collide with the particles of air. This slows down the diffusion rate. But in vacuum there are no particles to collide. Hence bromine diffuses faster in vacuum than in air.
What causes diffusion to occur?
For diffusion to occur there must be a concentration gradient. The dissimilarity in the amounts of solutes, particles, or molecules between the two regions will cause them to move between the two regions.
Why is diffusion faster in a vacuum?
In vacuum, since no air molecule is present, the molecules of the substance to be diffused don’t face any resistance or opposition. Thus, no collision and hindrance causing the diffusion to occur faster.
Why does bromine Vapour diffuse upwards?
Note: Kinetic energy of bromine is very high as compared to air and thus it tends to move upward and mix with air.
Why does diffusion take place?
Diffusion happens because gases and liquids move from place to place in quick random motions. When this happens, the particles collide, which in turn makes them change directions. The process of diffusion occurs on its own without any help from shaking or stirring.
How does diffusion process?
Diffusion helps in the movement of substances in and out of the cells. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout. Liquid and gases undergo diffusion as the molecules are able to move randomly.
What makes diffusion faster?
The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
