I never knew this either. This makes sense as when you tap on a propane tank they always sound empty, different than a metal tank of water. Even though it's a liquid and under extreme pressure, it's only the temperature that matters.
- thfuran 3y agoLiquid propane is definitely not an ideal gas.
- bongodongobob 3y agoNot saying it is, but it's very volatile. It really doesn't want to be a liquid at room temperature. I can't tell if it's empty or full when a tap on it, but definitely can with with water. It's an impedance thing.
- thfuran 3y agoI'm just saying a fact about ideal gases doesn't really imply anything about LP.
- bongodongobob 3y agoIt does, vapor pressure.

- nautilius 3y agoThat's got nothing to do with some fluid behaving like an ideal gas or not. Also, except for very low pressures, vapor does not behave like an ideal gas.
- bongodongobob 3y agoSure it does, it's riding the border of a phase change between gas and liquid. It's in a super compressed equilibrium so it's going to behave similarly to an ideal gas.
- nautilius 3y agoThat's - not how that works. I suggest you look at any fluid data `riding' that border. "Super compressed" and "ideal gas" are mutually exclusive. "Equilibrium" has even less to do with any of that.
- jldl805 3y agoThat's because propane tanks are only 1/4 full even when filled to max capacity.
