Question 33
Gas LawsThe pressure of 100cm3 of oxygen at 35°C is 750mmHg. What will be the volume of the gas if the pressure is reduced to 100mmHg without changing the temperature?
- A.650 cm3
- B.850 cm3
- C.580 cm3
- D.750 cm3
Show the answer and explanation
Answer: D (750 cm3)
Explanation
At constant temperature, Boyle's law: P1V1 = P2V2, so V2 = 750 × 100 / 100 = 750 cm3.
