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? (2 points) Some of the water molecules became vapor, then condensed back into droplets on the mirror. The water from the bath evaporated and turned solid on the mirror. The water in the bath solidified, then melted and evaporated before ending up on the mirror. Some of the water molecules condensed on the side of the tub, then melted back into vapor to travel to the mirror.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
