Humidity Is a Measure of the Amount of Water Vapor

Multiple Choice

Humidity is a measure of the amount of water vapor in the atmosphere. Why is humidity always very low inside your kitchen freezer?

A) because the kitchen freezer is most often sealed off from the atmosphere
B) because the frost in the freezer absorbs this moisture
C) because it is not possible for water to be in the gaseous phase at temperatures below 0°C
D) because at the cold temperatures of your kitchen freezer, water molecules in the vapor phase are moving relatively slowly, which makes it easier for them to stick to inner surfaces within the freezer or to other water molecules.
