How do you explain diffusion and osmosis?

How do you explain diffusion and osmosis?

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

How is equilibrium reached in diffusion and osmosis?

Equilibrium is reached when there is a uniform distribution of solvent particles or when there is an equal concentration of solute on each side of a membrane.

How does osmosis occur?

Osmosis occurs according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. Osmosis occurs when there is a concentration gradient of a solute within a solution, but the membrane does not allow diffusion of the solute.

How does equilibrium relate to diffusion?

Explanation: Diffusion means the movement of particles from an area of high concentration to an area of low concentration. Equilibrium means that a balanced situation has been achieved (particles are evenly spread out). Dynamic means that things continue to happen – the particles don’t stop moving!

Where do we see osmosis in real life?

when you keep raisin in water and the raisin gets puffed. Movement of salt-water in animal cell across our cell membrane. Plants take water and mineral from roots with the help of Osmosis. If you are there in a bath tub or in water for long your finger gets pruned.

What is diffusion Class 9 CBSE?

Diffusion- The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion. The diffusion of one substance into another substance goes on until a uniform mixture is formed.

What is an example of osmosis and diffusion?

The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food colouring is added to a glass of water, where eventually, the entire water content becomes coloured.

What is a must for osmosis to take place?

Semi-permeable membrane is a must for osmosis to take place. Movement or transportation in this process of osmosis tends to equalize the concentration of the solvent, which doesn’t occur although. 1. Osmosis is a special kind of diffusion.

Can diffusion take place in solid liquid and gas?

Only solvent (generally water) can move from the area of higher concentration to an area of lower concentration. Solid, liquid or gas, diffusion can take place in any of these media. No requirement of semi-permeable membrane for diffusion to occur. Semi-permeable membrane is a must for osmosis to take place.

How does diffusion occur in the cell membrane?

Diffusion happens in liquids and gases- the two phases in which particles have translational kinetic energy. And it can also happen across the cellular membrane. If there’s a high concentration of a substance outside of the cell, more substance will diffuse into than out of the cell, until the concentrations are equal.
