Question 13

Gas Laws

A certain volume of a gas at 298 K is heated such that its volume and pressure are now four times the original values. What is the new temperature?

  1. A.18.6 K
  2. B.100.0 K
  3. C.298.0 K
  4. D.1192.0 K
  5. E.4768.0 K
Show the answer and explanation

Answer: E (4768.0 K)

Explanation

PV/T is constant, so if P and V are each multiplied by 4, T is multiplied by 16: 298 × 16 = 4768 K.
