Question
A gas at 46 K is heated at constant pressure until its volume is doubled, what is its final temperature?
Correct Answer
Option D is the correct answer.
Detailed Explanation
For an ideal gas at constant pressure, volume is proportional to absolute temperature (Charles's law): V₁/T₁ = V₂/T₂. Given V₂ = 2V₁ and T₁ = 46 K, then T₂ = (V₂/V₁) × T₁ = 2 × 46 = 92 K.
Hint
Use Charles's law: V ∝ T at constant pressure.
