As the temperature of a material increases, what happens to its internal vapor pressure?

As the temperature of a material increases, its internal vapor pressure also increases. This is due to the kinetic theory of gases, which states that as temperature rises, the energy of the molecules within the material increases. This increased energy causes more molecules to escape from the surface of the liquid (or solid), transitioning into vapor and resulting in a higher vapor pressure.

In practical terms, this is essential for understanding the drying process in restoration and mitigation situations. For example, when materials are exposed to heat during the drying process, the increased temperature accelerates evaporation, reducing moisture content more efficiently. This principle of increased vapor pressure with temperature is critical in determining how effective drying strategies will be and is foundational knowledge for anyone involved in commercial drying efforts.
