Question

List the two factors which decide the direction of diffusion and oxygen and carbon dioxide. Explain.

Answer 1

The two factors that determine the direction of oxygen and carbon-dioxide diffusion are as follows :-

→ Concentration

The diffusion always takes place from the region of high concentration to the region of low concentration .

Hence we will notice that diffusion of oxygen will occur from the high concentration of oxygen to low concentration of it .

→ Pressure

The pressure caused by the movement of the surroundings also enable diffusion of the gases .

The pressure also causes movement in the molecules of the gases thus enabling fast diffusion .

Answer 2

Concentration and pressure

Concentration and pressure are 2 factors which decide the direction of diffusion and oxygen and carbon dioxide.

First of all, we know that diffusion of energy is always from high to low.

⬛️ Pressure ➡️ In this process oxygen and carbon dioxide are diffused from High pressure to low pressure. And because of having more pressure, Oxygen and co2 are diffused in pressurised condition.

Because of pressure, molecules moves rabidly and because of it diffusion occurs fast.

Pressure Enables diffusion of gases with the help of molecules.

⬛️ Concentration ➡️ In science, Concentration means transferring from High to low. And this the same process which is done in terms of Oxygen and CO2.

And because of highly concentration in Oxygen and CO2, concentration is done rapidly in this.
