was wondering if I am leaking or the drop from 1000-700 and slowly dropping is due to it being in the freezer at 40F and will it normalize?

[3rd party JKor]

its due to the temperature drop.

Thanks JK

PV=nRT

Well, in this case it's a saturated liquid and gas at equilibrium, so PV=nRT doesn't describe the relationship of pressure to temperature. Easiest way is to look a table of saturation temps and pressures.

Precisely.

Any time log charts show up, the thread is getting too technical.Plus, nobody's kegerator is at 150°K. Crop that chart!

The graphs and equations I've found put the vapor pressure of CO2 at kegerator temperatures of 34-40F at 520 to 580 PSI. This agrees with my pressure gauge readings.
