Question

If we keep hydrogen inflated ballon in the car in hot sunny day, what will happen to the volume and pressure inside the ballon?​

Answer 1

Answer:

Charle’s Law relates to volume, not pressure. The statement of Charle’s law is that as the balloon warms, the gas will expand. It’s a good first approximation.

The reality is that there will be a combination of expansion, and pressure increase, since increasing the size of the balloon requires further stretching the elastic membrane of the balloon. It’ll also increase the leakage rate, so the balloon will be losing gas faster. You can make it complicated very fast.
