Question

how does the pressure exerted by a gas inside a balloon compare to the pressure exerted on a balloon by the atmosphere?

p_{balloon}>p_{atmosphere}

p_{balloon}=p_{atmosphere}

p_{balloon}<p_{atmosphere}

rewatch

Explanation:

When a balloon is inflated, the gas inside exerts a pressure \(P_{balloon}\) on the walls of the balloon. The atmosphere exerts an external pressure \(P_{atmosphere}\) on the balloon. For the balloon to maintain its shape (not expand indefinitely or collapse), the pressure exerted by the gas inside the balloon must be greater than the atmospheric pressure. If \(P_{balloon}=P_{atmosphere}\), the balloon would be in a state of equilibrium but would not have the "tension" to hold its shape as we typically see (it would be like a deflated balloon in a vacuum - like situation which is not the normal case). If \(P_{balloon}

Answer:

\(P_{balloon}>P_{atmosphere}\)
