    (a) As temperature increases, the average kinetic energy increases

    (b) If H₂ is replaced with N₂, there will be increase in average velocity

    (c) An increase in temperature will cause increase in average velocity

    (d) The increase in entropy as a result of an increase in temperature and average velocity will cause the kinetic energy to increase.

    Explanation:

    Given;

    5.0L container filled with H₂ at stp

    Part (a) What happens to average kinetic energy as temperature increases

    As temperature increases, the average kinetic energy increases

    Part (b) What happens to the average velocity if H₂ is replaced with N₂

    Entropy is directly proportional to average velocity of gases and entropy increases with an increase in molecular mass. The molecular mass of nitrogen gas N₂ is greater than molecular mass of hydrogen gas H₂.

    Thus, if H₂ is replaced with N₂, there will be increase in average velocity.

    Part (c) What happens to the average velocity as temperature increases

    Kinetic energy increases with an increase in temperature and average velocity.

    An increase in temperature will cause increase in average velocity

    Part (d) What happens to average kinetic energy if H₂ is replaced with N₂

    The increase in entropy as a result of an increase in average velocity will cause the kinetic energy to increase.
