10. What is the term for the movement of gas molecules from an area of high concentration to an area of low concentration? Diffusion Effusion Compression Convection

## Step 1<br />The question is asking for the term that describes the movement of gas molecules from an area of high concentration to an area of low concentration. This process is known as diffusion.<br /><br />## Step 2<br />Diffusion is a passive process that does not require any energy input. It is a fundamental concept in the study of gases and is a key principle in many biological processes.<br /><br />## Step 3<br />The other options provided, effusion, compression, and convection, do not accurately describe this process. Effusion refers to the process where a gas escapes through a small hole into an evacuated space. Compression is the process of reducing the volume of a gas, and convection is the process of heat transfer through the movement of gases or liquids.
