Physics Question from JEE Main 2025 · 28 January, Shift 1

For a particular ideal gas, which of the following graphs represents the variation of mean squared velocity of the gas molecules with temperature?

Four graphs of mean squared velocity versus temperature labeled 1 to 4, where graph 3 is a straight line with positive slope through the origin.
  • A

    Graph 1 — mean squared velocity rising with an upward (concave) curvature

  • B

    Graph 2 — mean squared velocity rising and flattening off (concave down)

  • C

    Graph 3 — a straight line through the origin with positive slope

  • D

    Graph 4 — a peak that rises and then falls
