eli5 How do pressurized gas cylinders work?

Question

I’m wondering specifically about LPG bottes. I don’t understand how LPG can be stored as a liquid inside a pressurized bottle that is 80 degrees celsius when LPG’s boiling point is -42 degrees celsius. How does this work?

In: Chemistry

Answer 1

LPGs boiling point is -42 C AT STANDARD PRESSURE. Changing the pressure changes the boiling point.

For instance at about 125 psi (850 KPa), propane is liquid to about 21 C.

That’s the simplest answer that I have that is ELI5. Does that explain it well enough?
