Calculate the work done in joule if 1 mole of an ideal gas compressed from volume \(24 \mathrm{dm}^3\) to \(13 \mathrm{dm}^3\) at constant external pressure 3 bar.
- A 3300 J
- B 2250 J
- C 4400 J
- D 4870 J
Answer & Solution
Correct Answer
(A) 3300 J
Step-by-step Solution
Detailed explanation
\(\Delta V = (13 - 24) \mathrm{dm}^3 = -11 \mathrm{dm}^3 = -0.011 \mathrm{m}^3\) \(W = -P_{ext} \Delta V = -(3 \times 10^5 \mathrm{Pa}) \times (-0.011 \mathrm{m}^3) = 3300 \mathrm{J}\)
