I never have thought about storing temperature of the cylinder. Nepal has any type of climate always. I am living around 150km south from the tallest mountain Mt. Everest and here days are hotter like 38 to 40°C. Just 150km north in there is snowfall always.yes, and that is fairly warm. keep the cylinder out of direct sunlight, and away from surfaces that radiate a lot of heat like asphalt road or parking lot surfaces. i'm guessing Nepal at this time of year is kind of a hot climate.
Here is a bottle half full of liquid and half of gas. (well probably air which is CO2 and many things) The gas could be water vapor like a cloud. You can have water as a liquid and as a gas at the same temperature and pressure.Maybe gas above the liquid creates pressure but why there's liquid propane and gas propane both created in a same tank?

Get a bottle with a vacuum in it. (nothing there, like space) Fill it 1/2 full of water. About 0.1% of the water will turn to gas to fill up the vacuum. Now you have a bottle with 49.1% liquid water and 50.1% water gas. By weight the bottle is 1/2 full. If you tried to put more liquid water in the bottle the more pressure will force some of the gas back to liquid. If you removed some of the water the reduced pressure will allow more liquid to move to gas.
Wow! The baloon floats just because of 'hot air'? I think the baloon's material is a hot resistance so it does not melt. What is the temperature inside the baloon while floating?I've been a hot air balloon pilot for 38 years so I've gotten very close and personal with propane.
it really doesn't take much of a difference in temperature, as long as the difference in density between the inside and outside air provides enough buoyancy to lift the mass of the balloon and it's occupants.Wow!

that would also mean that the pressure differential in the walls of the container are still what is indicated on the gauge, or at least fairly close. that additional 153mb is exerting a force on the walls of the container. that's why there are two common measurements, psia (absolute pressure) and psig (gauge pressure). at sea level, 15psia=0psig. if a container were sealed at sea level, a gauge attached to it would read 0psig, and would read 15psig when placed in a vacuum. at STP, the container has no pressure differential applied to the container walls, but in a vacuum, there's a pressure differential of 15psi, and that force is applied to the walls of the container.
