The pressure of an ideal gas is increased by keeping the temperature constant. What happens to the mean free path of the gas molecules?
- A.It increases
- B.It decreases
- C.It remains constant
- D.It becomes zero
Show correct answer & step-by-step solution
Correct answer: B — It decreases
Solution
The mean free path is given by . Since temperature is constant, . Therefore, increasing pressure results in a decrease in .
