Question

Calculate the work associated with the expansion of a gas from 46 L to 64 L against a constant external pressure of 15 atm (1 atm = 101,325 Pa).
Options
A -27,358 J
Correct Answer
B +27,358 J
C -18,239 J
D +18,239 J
Correct Answer

Option A is the correct answer.

Detailed Explanation

w = -PΔV = -(15 * 101325 Pa) * ((64 - 46) * 10^-3 m³) = -27357.75 J ≈ -27,358 J.
