Question

Helium has the lowest boiling point of the elements. The slightest change in temp can cause it to vaporize and expand. To prevent pressure explosions, a line from the tank has a "burst disk" in case a of sudden pressure increse. then the diaphragm would rupture and release the gas before pressure was too high.

This is an example of which physics law? Charles? Boyle? Ideal?

I think possibly Charles because as it warmed up due to the fire, the pressure expanded and it exploded. Temp increase, pressure increase. please help
