The pressure of 'V' litres of a dry gas is increased from 1 to 2 kgf/cm2 at a constant temperature. The new volume will become___________________?
Correct answer: A. V/2
- A. V/2
- B. 2V
- C. V/4
- D. V2
Explanation
At constant temperature, Boyle's law gives P₁V₁ = P₂V₂. Doubling the pressure from 1 to 2 kgf/cm² therefore halves the volume to V/2.
