JEE Main & Advanced Chemistry States of Matter / पदार्थ की अवस्थाएँ - गैस एवं द्रव Question Bank Molecular speeds

  • question_answer
    At constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with increase in temperature due to   [IIT 1992]

    A)                 Increase in the average molecular speed

    B)                 Increased rate of collision amongst molecules

    C)                 Increase in molecular attraction

    D)                 Decrease in mean free path

    Correct Answer: A

    Solution :

                    When average speed of molecule is increased due to increase in temperature then the change in momentum during collision between wall of container and molecules of gas also increases.
