Effusion:
Imagine you're trying to leave a crowded concert hall through a small side door, and everyone wants to get out at the same time. This situation is similar to effusion, where gas molecules escape from a container through a tiny hole because of a pressure difference. Just as people in the concert hall are pushed towards the exit due to the pressure of the crowd, gas molecules are driven through the small opening by the pressure inside the container being higher than outside, and the tiny door acts like the small hole through which only a few can pass at a time.
