Explain why diffusion?

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.

How do you explain diffusion?

Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things - it is how substances move in and out of cells.

Why does diffusion happen?

Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration. Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions - but diffusion does not occur in solids.

What is diffusion in biology?

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. ... The difference in the concentration of a substance between two areas is called the concentration gradient .

What is diffusion give an example class 9?

Hint: Simple diffusion can be described as a process in which the movement of substances occurs via a semipermeable membrane or in a solution without any help from transport proteins. The examples of simple diffusion can be bacteria delivering small nutrients, movement of water and oxygen into the cytoplasm.

How do you explain diffusion to a child?

Diffusion is a physical process where molecules of a material move from an area of high concentration (where there are many molecules) to an area of low concentration (where there are fewer molecules). Diffusion usually happens in a solution in gas or in a liquid.

What is diffusion in your own words?

1 : the act of spreading or allowing to spread freely. 2 : the mixing of particles of liquids or gases so that they move from a region of high concentration to one of lower concentration. diffusion.

What is diffusion and why is it important?

Diffusion can occur across partialy permeable membranes, such as those surrounding cells. Therefore, diffusion is involved in the movement of important molecules into and out of cells. It is important for the uptake of substances needed by cells, and also the removal of waste products produced by the cells.

What diffusion means?

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.

What is diffusion process in physics?

Diffusion is the movement of particles move from an area of high concentration to an area of low concentration until equilibrium is reached. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. ... The result of diffusion is a gradual mixing of material.

What is diffusion in Brainly?

Brainly User. Answer: Diffusion is the movement of water molecules from an a region of higher concentration of the molecules to a region of a lower concentration.......

What is diffusion class 10th?

Answer: Diffusion is the process of movement of molecules under a concentration gradient. ... 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 is diffusion Class 9 short answer?

Diffusion- The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion. It is one of the properties of materials. The diffusion of one substance into another substance goes on until a uniform mixture is formed. Diffusion takes place in gases, liquids and solids.

What is diffusion explain with two examples?

(a) Diffusion is the mixing of a substance with another substance due to the motion of its particles. The smell of perfume spreads over a whole room is an example for diffusion. (b) Gases diffuse fast because of the large space between the particles in gases and high kinetic energy.

How do you teach diffusion?

There are some great demonstrations to observe diffusion. Give students a stop clock and ask them to record when they first smell deodorant that has been sprayed in the middle of the class. If you also get students to raise their hands when they first smell the deodorant you will get a lovely ' mexican wave' effect.

How would you describe what diffusion is to a fourth grader?

Diffusion is the movement of particles from where there are more to where there are less.
