PVT는 일정. 0.50 mol O2 0℃ 1 atm volume half 2.2 atm. T2 계산

 

 

A 0.50 mol sample of oxygen gas is confined

at 0℃ and 1.0 atm in a cylinder with a movable piston.

The piston compresses the gas so that

the final volume is half the initial volume

and the final pressure is 2.2 atm.

What is the final temperature of the gas in ℃?

 

---------------------------------------------------

 

P1V1 / T1 = P2V2 / T2

( 참고 https://ywpop.tistory.com/7091 )

 

 

 

the final volume is half the initial volume

---> V1 = 10 L 라 두면,

V2 = 5 L.

 

 

 

T2 = P2V2 / [P1V1 / T1]

= (2.2) (5) / [(1) (10) / (273.15 + 0)]

= 300.47 K

 

 

 

300.47 – 273.15 = 27.32℃

 

 

 

답: 27℃
