Question 5
Gas LawsThe volume of a given gas is V cm3 at P mm Hg. What is the new volume of the gas if the pressure is reduced to half at constant temperature?
- A.4V cm3
- B.2V cm3
- C.V/2 cm3
- D.V cm3
Show the answer and explanation
Answer: B (2V cm3)
Explanation
Boyle's law: PV is constant, so halving the pressure doubles the volume to 2V.
