Question

What is Diffusiom and Osmosis​

Answer 1

Diffusion

Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. .

osmosis

Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.

Answer 2

Here's your answer! ❤

DIFFUSION

Diffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. A good example of diffusion is food colouring. If you place a drop of red food colouring in a beaker of water eventually the entire beaker of water will have a red tint. The food colouring moved through the water until it was equally distributed throughout the beaker. Diffusion takes place along a concentration gradient. A concentration gradient exists until the diffused substance is evenly distributed.

Other everyday examples of diffusion are:

1. Sugar will diffuse through tea until the entire cup of tea is sweet. (We stir the tea to speed up the diffusion.)

2. The odour of food cooking diffuses throughout the kitchen. If you open the kitchen door it will spread into the next room.

The movement of these molecules is said to be passive. No energy is needed to be provided. The natural kinetic energy of the particles supplies the energy.

Examples of diffusion in science are:

1. Carbon dioxide entering the stomata of leaves.

2. Oxygen diffusing out of the stomata and lenticels of leaves.

Osmosis

Osmosis is the result of diffusion across a semipermeable membrane from a lower concentration to a higher one.

Explanation:

If two solutions of different concentration are separated by a semipermeable membrane, then the solvent will tend to diffuse across the membrane from the less concentrated to the more concentrated solution. Diffusion occurs when the spontaneous net movement of particles or molecules spreads them from an area of high concentration to an area of low concentration through a semipermeable membrane.

Osmosis is a process in which a fluid passes through a semipermeable membrane, moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute is present in high concentrations.

The end result of osmosis, barring external factors, will be equal amounts of fluid on either side of the barrier, creating a state which is known as “isotonic.” -
