The state of an ideal gas was changed isobarically. The graph depicts three such isobaric lines. Which of the following is true about the pressures of the gas?

Options

  1. AP ₁= P ₂= P ₃
  2. BP ₁> P ₂> P ₃
  3. CP ₁ < P ₂ < P ₃
  4. DP ₁ / P ₂= P ₃ / P ₁

Correct answer

B. P ₁> P ₂> P ₃

Step-by-step solution

For constant temperature P 1 V V ₃> V ₂> V ₁ so P ₃ < P ₂ < P ₁
