Which of the following relationship when graphed give a rectangular parabola for helium gas? I. KE vs T at constant P and V II. V vs 1 T at constant P and n III. P vs V at constant T and n

Options

  1. AIII
  2. BI and III
  3. CII
  4. DII and III

Correct answer

D. II and III

Step-by-step solution

Graph of P vs V at constant T is a rectangular parabola. Graph of V vs 1 T at constant P and n is a rectangular parabola. Kinetic energy ∝ T Hence a graph between KE v/s T will be in straight line.
