When the liquid reaches its boiling point, ___________________________. Choose all that apply.

Question

A> The vapor pressure of the liquid at normal condition is equal to 760 torr.

B> The sigma and pi bonds are broken.

C> The gas that forms in the liquid escape in the form of bubbles.

D> The temperature rises as heat is added.

E> The liquid is no longer evaporating.

Im not sure what happens to sigma and pi bonds when a liquid boils...I chose C and D, but Im not sure which others to choose because I thought hear was escaping thru vaporization but not in the form of bubble, can someone explain?

Answer 1

The correct choices are A and C.

A. By normal conditions, I assume you mean standard atmospheric pressure. In that case the vapor pressure would be 760 torr.

C. The gas that forms does form bubbles in the liquid.
