Questions & Step-by-Step Solutions
In a gas, the mean free path is defined as the average distance traveled by a molecule between collisions. Which factor does NOT affect the mean free path?
Step 1: Understand what mean free path means. It is the average distance a molecule travels before hitting another molecule.
Step 2: Identify the factors that can affect the mean free path. These include temperature (how hot or cold the gas is), pressure (how much gas is in a given space), and molecular diameter (the size of the gas molecules).
Step 3: Recognize that some factors do not affect the mean free path. For example, the color of the gas does not influence how far molecules travel before colliding.
Step 4: Conclude that while temperature, pressure, and molecular diameter are important, the color of the gas is not a factor that affects the mean free path.
