How much moisture can one cubic foot of air at 50 deg F absorb compared to air at 100 deg F?

Air can hold varying amounts of moisture depending on its temperature. At 100 degrees Fahrenheit, air has a greater capacity to absorb water vapor than at 50 degrees Fahrenheit. This is due to the fact that warmer air molecules move more quickly, allowing them to hold more moisture.

When considering a cubic foot of air, the amount of moisture it can absorb increases with temperature. Therefore, when comparing air at 50 degrees Fahrenheit to air at 100 degrees Fahrenheit, the cooler air lacks the capacity to hold as much moisture. Consequently, one cubic foot of air at 50 degrees Fahrenheit can absorb less moisture than the same volume of air at 100 degrees Fahrenheit. This fundamental principle of thermodynamics and psychrometrics explains why the correct answer is that air at 50 degrees Fahrenheit can absorb less moisture compared to air at 100 degrees Fahrenheit.
