0.985 atm volume 1.55 L 0.85 L contract work

 

 

Calculate the work, in J, if the volume of a system contracts

from 1.55 to 0.85 L at a constant pressure of 0.985 atm.

 

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

 

w = –P•ΔV

( 참고 https://ywpop.tistory.com/6336 )

 

= –(0.985) (0.85 – 1.55)

= 0.6895 atm•L

 

 

 

(0.6895 atm•L) × (8.314 J / 0.08206 atm•L)

= (0.6895) × (8.314 / 0.08206)

= 69.86 J
