Which of the following statements correctly describes the change which occurs when a liquid vaporizes at its boiling point at a given external pressure.

a) The entropy decreases
b) The temp increases
c) The kinetic energy increases
d) The potential energy increases

I can't eliminate any answers at all, thanks in advance.

  • Chemistry -

    The entropy is greater in steam than in liquid so a is gone.
    The temperature stays constant at the boiling point when liquid is vaporized so b is gone.

  • Chemistry -

    So it is c because the molecules move faster in gas. Thank you!
