What is the work done on an ideal gas during an isobaric expansion from 0.02 m^3 to 0.05 m^3 at a constant pressure of 100,000 Pa?

Answer and explanation

Correct answer: D. 3,000 J

  1. Step 1: Work done during isobaric process is W = P * delta_V.
  2. Step 2: Calculate change in volume: delta_V = V_final - V_initial = 0.05 - 0.02 = 0.03 m^3.
  3. Step 3: Multiply by pressure: W = 100,000 Pa * 0.03 m^3 = 3,000 J.
Answer
3,000 J.
Why not the others: '5,000 J' uses V_final alone; '2,000 J' uses V_initial alone; '7,000 J' adds both volumes together.
