  • question_answer Which one of the following statements is NOT true about the effect of an increase in temperature on the distribution of molecular speeds in a gas             [AIEEE 2005]

    A)                 The most probable speed increases

    B)                 The fraction of the molecules with the most probable speed increases

    C)                 The distribution becomes broader

    D)                 The area under the distribution curve remains the same as under the lower temperature

    Correct Answer: B

    Solution :

                    Most probable velocity increase and fraction of molecule possessing most probable velocity decrease.
