Gay-Lussac's Law (P,/T, P./T) 8. A steel bomb having a volume of 575 cm3 is filled with air at 28°C and 0.85 atm. If the bomb was filled with 575 cm3 of air at 2.0 atm of pressure, what is the temperature of the air? vessel is heated to 225°C, what is the new pressure of the argon gas? ampule is stored in a -80°C freezer, what is the new pressure of helium within the ampule? 9. A sealed glass vessel with a 50.0 L volume is filled with argon gas at 22°C and 1.0 atm. If the 10.A glass ampule is filled with helium gas and is sealed at a pressure of 1.0 atm and 25°C. If the

Explanation / Answer

8

P1/T1 = P2/T2

0.85 / ( 28+273) = 2 / T2

T2 = 2*(28+273)/0.85 = 708.23 K = 708.23 - 273 = 435.23 C

9

P1/T1 = P2/T2

1/(22+273) = P2/(225+273)

P2 = (225+273)/(22+273) = 1.688 atm

10

P1/T1 = P2/T2

1/(25+273) = P2/(-80+273)

P2 = (-80+273)/(25+273) = 0.6476 atm
