Question 14
Gas LawsA column of air 10.0 cm long is trapped in a tube at 27°C. What is the length of the volume at 100°C?
- A.12.4 cm
- B.13.7 cm
- C.18.5 cm
- D.37.0 cm.
Show the answer and explanation
Answer: A (12.4 cm)
Explanation
At constant pressure V ∝ T (kelvin), and V ∝ length for a uniform tube: L = 10 × 373/300 ≈ 12.4 cm.
