Rubber balloon filled with `H_(2)` gas gets deflated after some time-explain why?

Text Solution

Verified by Experts

As rubber is a porous substance, a rubber balloon contains many invisible pores in its surface. The balloon contains `H_(2)` gas at high pressure. But the pressure of air outside the balloon being comparatively lower. As a result, `H_(2)` gas escapes from the balloon by effusion. this is why the pressure inside the balloon gradually falls and affter some time the balloon gets deflated.
