1.02 atm 0.055 L 1.403 L expand L•atm work

 

 

If a balloon is expanded from 0.055 to 1.403 L

against an external pressure of 1.02 atm,

how many L-atm of work is done?

 

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

 

w = –P•ΔV

( 참고 https://ywpop.tistory.com/6336 )

 

= –(1.02) (1.403 – 0.055)

= –1.375 atm•L
