Question 5
Gas LawsA gas sample with an initial volume of 3.25 dm3 is heated and allowed to expand to 9.75 dm3 at constant pressure. What is the ratio of the final absolute temperature to the initial absolute temperature?
- A.3:1
- B.5:2
- C.5:4
- D.8:3
Show the answer and explanation
Answer: A (3:1)
Explanation
By Charles' law, V/T is constant at fixed pressure, so T2/T1 = V2/V1 = 9.75/3.25 = 3, a ratio of 3:1.
