Which of the following statements describes what will occur to the volume of water vapor as it is exposed to the lower temperatures existing in the device labeled "24" shown in the illustration? Illustration MO-0111

Correct Answer: Option C — The volume is greatly reduced, contributing to condensation within the condenser.

Condensation involves a phase change from vapor to liquid. As water vapor enters the condenser (device 24) and contacts the cooling tubes, the latent heat of vaporization is removed. This phase change causes a massive reduction in specific volume, creating the vacuum necessary to sustain the distillation process.
