Question 8

Gas Laws

Which of the curves W, X, Y and Z in the graph of PV/RT against P illustrates the behaviour of an ideal gas?

Diagram for this question
  1. A.W
  2. B.X
  3. C.Y
  4. D.Z
Show the answer and explanation

Answer: C (Y)

Explanation

For one mole of an ideal gas PV = RT, so PV/RT = 1 at every pressure. That is the horizontal line Y.
