How do people get pure gases? (e.g, a helium tank for balloons)
In: Physics
I believe OP is asking how different gases are extracted to fill a tank.
At least, that’s what I gather.
I don’t know how an oxygen generator works to pull O2 from the air, but I assume the same type of process would work for helium (I assume it’s somehow extracted from the breathing air vs. Things like natural gas, which come from underground)
