Question

Give It Some Thought 10.11 Will these changes increase, decrease, or have no effect on the mean free path of the molecules in a gas sample? Part A increasing pressure It will increase the mean free path of the molecules in a gas sample. It will decrease the mean free path of the molecules irn a gas sample. It will have no effect on the mean free path of the molecules in a gas sample. Submit Give Up Part B increasing temperature It will increase the mean free path of the molecules in a gas sample.

Explanation / Answer

As gas density increases, the molecules become closer to each other. Therefore, they are more likely to run into each other, so the mean free path decreases

Pressure, temperature, and other factors that affect density can indirectly affect mean free path.

A)

Pressure will increase the density of gas.

So mean free path will decrease .

B) Temperature will decrease the density of gas.

So mean free path will increase
