Boyle's law states that, at constant temperature, the volume of a fixed mass of gas is:

  1. A. Directly proportional to pressure
  2. B. Inversely proportional to pressure✓ Correct answer
  3. C. Directly proportional to temperature
  4. D. Independent of pressure

Explanation

Boyle's law: PV = constant at constant temperature and amount of gas, so V ∝ 1/P. Doubling the pressure halves the volume.

بوائل کا قانون: درجہ حرارت اور گیس کی مقدار مستقل ہو تو PV مستقل رہتا ہے، یعنی V ∝ 1/P۔ دباؤ دگنا کریں تو حجم آدھا ہو جاتا ہے۔
