Title: Temperature vs Pressure of Gas
Post by: Joey_leal2020 on February 14, 2018, 06:58:52 PM

I had a question on a gas laws quiz today, assuming the gas is following the kinetic molecular theory. In went like this, "I have a gas in an inflated, expandable container. If I raise the temperature of the gas, what would happen to the pressure?" I said that the pressure would not change, because if the container is EXPANDABLE, wouldn't that mean that itakes volume would increase to maintain the same pressure inside?

Yes correct

I'd have preferred a formulation like "expandable with no effort" of "freely expandable". A tyre tube for instance is expandable but needs some pressure to increase its volume.

Plus "a state of being inflated" is ambiguous about whether further inflation is possible.
All in all, not a very well written problem.
