What is the relationship between the mean free path (λ) and the diameter (d) of gas molecules?
Correct Answer: Mean free path (λ) inversely proportional hai diameter (d) se.
- Step 1: Understand what mean free path (λ) means. It is the average distance a gas molecule travels before colliding with another molecule.
- Step 2: Know that the diameter (d) of gas molecules is the size of each molecule.
- Step 3: Realize that if gas molecules are larger (bigger diameter), they will collide more often, which means the mean free path (λ) will be shorter.
- Step 4: Conversely, if gas molecules are smaller (smaller diameter), they will collide less often, leading to a longer mean free path (λ).
- Step 5: This means that the mean free path (λ) is inversely related to the diameter (d) of the gas molecules. If one increases, the other decreases.
