Answer:

-27 kJ

Step-by-step explanation:

Given data

  • Initial volume (Vi): 46 L
  • Final volume (Vf): 64 L
  • External pressure (P): 15 atm

We can find the work (w) associated with the expansion of a gas using the following expression.

w = - P . ΔV

w = - P . (Vf - Vi)

w = - 15 atm . (64 L - 46 L)

w = -270 atm.L . (101.325 J/ 1 atm.L)

w = -2.7 × 10⁴ J

w = -27 kJ
