What does Graham's Law describe in relation to diffusion?

Thermal changes
Pressure changes
Overcoming hypoxia
Rate of diffusion of gases

The correct answer is: Rate of diffusion of gases

Graham's Law specifically addresses the rate of diffusion of gases and provides insights into how different gases behave under various conditions. It states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass. This means that lighter gases will diffuse faster than heavier gases, which is a crucial concept in understanding how gases interact and spread through mediums. In practical terms, this principle is essential for transport nurses as it can impact how various gases, such as oxygen and carbon dioxide, are administered and monitored in patients. Understanding the diffusion rates can help in assessing respiratory function and the effectiveness of treatments aimed at addressing issues related to gas exchange. By recognizing how the properties of different gases affect their diffusion rates, healthcare professionals can make better-informed decisions in critical care scenarios.
