Title: O2 tanks and summer heat
Post by Jeannie on Jun 9^th, 2011 at 5:09pm

It's been in the upper 90's here. Is it okay to keep my E Tanks in the car when it's that hot?

Thanks!

Jeannie

From personal experience only, I keep a D-tank in my car year-round. The last few days it's been in the upper 90's and my car is still intact.

Gay-Lussac's law states that for an ideal gas

p ~ T

i.e. pressure is proportional to the absolute temperature.

Since oxygen is very close to an ideal gas, we can calculate the following example:

Starting at 'room temperature' of 20 C or 293 K absolute temperature (68 F in the old money) we must heat up the tank to 313 C or 586 K (1055 F on your weird scale) to double the pressure.
So, if you don't park your car in a forest fire, you shouldn't worry about an exploding tank.
