Question

Relative partial pressure of gases determines the:

a. rate and direction of diffusion
b. rate but not the direction of diffusion
c. direction but no the rate of diffusion
d. neither direction nor rate of diffusion; you re thinking of convection

Answer 1

The relative partial pressure of gases determines (a) the rate and direction of diffusion.

Step-by-step explanation:

The relative partial pressure of gases determines the rate and direction of diffusion

The rate of diffusion is influenced by several factors, including the concentration gradient, the surface area available for diffusion, and the distance the gas particles must travel. However, the partial pressure of a gas within a mixture of gases determines the overall rate and direction of diffusion. This means that gases with higher partial pressures will diffuse more quickly and in a specific direction.

For example, if we have a higher partial pressure of oxygen in the alveoli of the lungs compared to the blood, oxygen molecules will diffuse from the alveoli into the blood. On the other hand, if the partial pressure of oxygen in the blood is higher, oxygen molecules will diffuse from the blood into the alveoli.
