A container of carbon dioxide has a pressure of 775mm Hg at 325k. If the temperature is decreased to 295k what is the pressure of the gas in the container? Please show work!!

Answer 1

P1 = 775 mm Hg

T1 = 325K

P2 = ?

T2 = 295K

At constant volume, you are dealing with Gay-Lussac's Law (review it if not familiar)

P1/T1 = P2/T2 and solving for P2...

P2 = P1T2/T1 = (775 mm)(295)/325 = 703 mm Hg
