Question

In a partitioned chamber, one kilogram of water vapor at 200 kPa fills one side. What is the process called?

A) Condensation
B) Evaporation
C) Sublimation
D) Compression

Answer 1

OPTION A.The process described in the question is called condensation, where water vapor transitions into a liquid state.

Step-by-step explanation:

The process described in the question, where one kilogram of water vapor at 200 kPa fills one side of a partitioned chamber, is called condensation.

Condensation is the process by which a gas is converted into a liquid. In this case, the water vapor is coming into contact with a cool surface, causing the vapor to lose energy and transition into a liquid state. The result is the formation of liquid water on one side of the partition.

For example, if you take a hot shower and notice water droplets forming on a cold mirror in the bathroom, that is condensation occurring. The water vapor in the air is condensing onto the cool mirror surface.
