which statement describes effusion?\nit occurs when a gas passes through a tiny hole.\nit occurs when a liquid passes through a tiny hole.\nit occurs when gas molecules disperse throughout a container.\nit occurs when a liquid disperses throughout a container.
Answer
Brief Explanations:
Effusion is the process where a gas passes through a tiny hole. This is based on the kinetic - molecular theory of gases. Liquid passing through a hole is not effusion, and gas molecules dispersing throughout a container is diffusion, not effusion. Liquid dispersing throughout a container is also not effusion.
Answer:
It occurs when a gas passes through a tiny hole.
