A water molecule starts in hot bath water and ends up on the surface of the bathroom mirror. Which of the following most likely happened during the transition?

A. Some of the water molecules became vapor, then condensed back into droplets on the mirror.

B. The water from the bath evaporated and turned solid on the mirror.

C. The water in the bath solidified, then melted and evaporated before ending up on the mirror.

D. Some of the water molecules condensed on the side of the tub, then melted back into vapor to travel to the mirror.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
