WebAug 6, 2024 · Diffusion occurs when gas molecules disperse throughout a container. Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time. If a mixture of gases is … WebThe alveoli are adapted to make gas exchange in lungs happen easily and efficiently.

Diffusion is defined as intermixing two or more gases at a given temperature, and pressure. It is random movement from the region of higher pressure to lower pressure along the concentration gradient. Concentration gradient is defined as concentration per unit length. Diffusion occurs in liquids and gases but hardly in solid.
