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