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

Question

freezer?
a) because the freezer is sealed off from the atmosphere
b) because the frost in the freezer absorbs moisture
c) because it is not possible to be in the gaseous phase below O degrees celsius
d) because at cold temperatures water molecules in the vapor phase move slowly, making it easy for them to stick to each other or the contents of the freezer

Answer 1

c

Answer 2

Humidity is the amount of water in the air at a certain temperature.

Dew point is the temperature at which water vapor falls out of the air into liquid or solid depending how low the temperature.

as the air in the freezer chills to -20 deg. C (freezer temperature) it passes through the dew point of water and a majority of water falls out to form frost.

so C. is mostly correct - but some small amount of water can be gaseous
until about -40 deg C

hope this helps
