Key Insights

Temperature Effect: The maximum moisture content in air increases significantly with temperature
Exponential Relationship: The relationship is not linear; small temperature increases at lower temperatures have less effect than at higher temperatures
Practical Application: This explains why heated air is far more effective than cold air in drying processes
Example: Air heated from 20°C to 50°C increases its moisture carrying capacity by approximately 380%

Note

Values are given in g/m³ (grams per cubic meter), which equals 10⁻³ kg/m³
Alternative unit: lb/ft³ (pounds per cubic foot)
