Question:
A helium-filled balloon spontaneously deflates overnight as He atoms diffuse through the wall of the balloon. Describe the redistribution of matter and/or energy that accompanies this process.
Effusion
Effusion is a process of escaping of gas from a container through a hole of diameter smaller than mean free path and this hole is pinhole and escape of gas is due to pressure difference.
