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.

As water vapor enters the condenser (device 24), it is exposed to cold tube surfaces. The removal of latent heat causes the vapor to undergo a phase change into liquid. This transition results in a massive reduction in volume, which sustains the vacuum necessary for low-temperature evaporation within the distiller shell.
