Assertion: When an ideal gas is compressed isothermally the number of collisions per second with the walls rises.
Reason: The mean free path of the molecules decreases when the volume is reduced.
Options:
Answer:
A
Solution:
At constant the average speed does not change. A smaller volume means a shorter mean free path and more collisions with the wall per second, which gives a higher pressure. A.
