Question 5

Gas Laws

A given mass of gas occupies 2 dm3 at 300 K. At what temperature will its volume be doubled keeping the pressure constant?

  1. A.400 K
  2. B.480K
  3. C.550 K
  4. D.600 K
Show the answer and explanation

Answer: D (600 K)

Explanation

Charles' law: at constant pressure volume is proportional to kelvin temperature. Doubling the volume needs double the temperature: 2 × 300 K = 600 K.
