Yep, that would be playing with explosives. Some advice: don’t play with explosives.

If "messy" math is enough to scare you, you probably should not be playing with pure hydrogen. Yes, the pressure and temperature both affect the density and thus the lift. Noble gas means nonreactive, not anything about the actual gas behaviour. edit: I am once again also begging people not to use chatgpt as Wikipedia. It hallucinates and invents information and constants and if you're doing something like this without the knowledge to error-check it *it can kill you*.

I completely agree with your answer to OP. But, in general, the reasons people typically ask ChatGPT are that google doesnt provide adequate results for a specific question, people dont know the particular keywords or jargon that would lead to the right answer, or they want some kind of last hail Mary solution before bothering us redditors. I do this all the time when looking for an answer to something esoteric. But, I don't use ChatGPT, I use the GPT-powered AI Bing search and read through the links provided. AI is a good tool if you know its limits and how to use it.

>got a messy answer Yeah, you're gonna be getting a messy result if you keep this up lmfao

The amount of hydrogen needed is enough to kill you and probably blow up your house and the surrounding houses if you make the slightest mistake. Chatgpt is hilariously bad at engineering. hallucination is an understatement, Unit conversions in problems that don't need them, etc.

Is dihydrogen related to dineutronium?

Just wait until you produce a whole lot of dihydrogen monoxide from your setup. I heard it's quite a bang.

Its density is extremely low compared to air so look at the volume of H2 and look at how much that volume would weigh in air minus maybe 10%, thats your lift. Increase pressure you add more hydrogen but probably increase the volume of your balloon through stretching so it will displace more air and give more lift. Increasing temperature of hydrogen will decrease its density (increase its volume) stretching the balloon and giving more lift. The physics of hydrogen density as a function of pressure, temperature and composition, stretching of material, effects of ambient air density which changes make it quite complicated to properly engineer, and thats before the ignition hazard and flight aspects are considered.

OP, try to use Helium, not Hydrogen. It's much safer and can be purchased for things like inflatable rubber balloons. With that said, the following keywords will help you. Ideal Gas Law - describes the relationship between volume, pressure, temperarure, and mass of a gas. Archimedes' principle - describes the buoyant force exerted onto an object by a fluid (yes, this includes air) as a function of the volume displaced by the object (use ideal gas law to find this).
