(adsbygoogle = window.adsbygoogle || []).push({}); 1. There is gas tank, contains 5 liters of CO2 under pressure 14.7 MPa, temperatute is 300K. I try to calculate, what temperature gas will have after release (to atmospheric 0.1 MPa and 2000 liters volume). But I cannot :(

2. volume * pressure / temperature = const

3. The attempt at a solution

To simplify, lets say it releases without any other expenses and all at once (ideal container without ability to transfer or store energy, no resistence from atmospheric air, etc).

5 liters *14.7 MPa /300Kelvin = 2000 liters *0.1 MPa /t2

73.5/300 = 200 /t2

0.245=200/t2

t2=816. Whoa! It become hot instead!

Can anybody point me where I am wrong?

Thank You.
