A fixed mass of gas at constant temperature has volume 6 cm at 300 kPa. The volume is reduced to 3 cm. What is the new pressure?
Answer and explanation
Correct answer: B. 600 kPa
- Step 1: At constant temperature (Boyle's law).
- Step 2: kPa.
Answer
600 kPa.
Why not the others: 150 kPa: it treats pressure as directly proportional to volume. 303 kPa: it adds the change in volume to the pressure. 1200 kPa: it doubles the correct value.
