If the absolute temperature of an ideal gas is tripled and simultaneously the pressure is reduced to one third; then the volume of gas will _______________?
Correct answer: B. Increase nine fold
- A. Remain unaltered
- B. Increase nine fold
- C. Increase three fold
- D. Decrease three fold
Explanation
For a fixed amount of ideal gas, volume varies directly with absolute temperature and inversely with pressure: V ∝ T/P. Tripling T and reducing P to one third multiplies the volume by 3 ÷ 1/3 = 9.
