If a soap bubble expands, the pressure inside the bubbleNEET 2022 (Phase 1)

Answer:

Solution:

A soap bubble has two liquid surfaces in contact with air, one inside the bubble and the other outside the bubble.

For pressure, we can write:

$P_{i} = P_{o} + \frac{4 T}{r}$ , so as $r$ increases, pressure inside the bubble decreases.
