Water Sorption Isotherm

A water sorption isotherm describes how much moisture a material absorbs or releases at different humidity levels, usually at a constant temperature. It shows the relationship between the relative humidity in the environment and the amount of water the material holds, providing valuable information about its stability, durability, and quality. This concept helps in understanding how materials like food, pharmaceuticals, or packaging behave when exposed to varying moisture conditions, ensuring proper storage and usage.
