@z14g2000cwz.googlegroups.com: Well, if I figured this right: P = n * R * T / V Whe P = pressure in atm n = amount of substance in moles R = Thermal expansion ( 1atm / K*mol ) T = Temp change in Kelvins V = Volume of a sealed container in Liters ( n ) for CO2 is 22.727mol ( R ) for CO2 is 0.08206 ( T ) is 298K ( V ) is 6.81322 Liters Ignoring the air present in the container when it was sealed, and introducing 1 Kg (2.2lbs) of dry ice in my 6.813 L tank, while the air in my living room is 24 C (75 F) final pressure inside the tank will be 8238.7 psi. Oh, crap. Well look on the bright side, if your tank doesn't hold, your manner of death will be posted on the next list of the Darwin Awards :P P. |
