Question 5

Gas Laws

At 25°C and 1 atm, a gas occupies a volume of 1.50 dm3. What volume will it occupy at 100°C and 1 atm?

  1. A.1.88 dm3
  2. B.6.00 dm3
  3. C.18.80 dm3
  4. D.60.00 dm3
Show the answer and explanation

Answer: A (1.88 dm3)

Explanation

At constant pressure V2 = V1 × T2/T1 = 1.50 × 373/298 = 1.88 dm3. Temperatures must be in kelvin.
