What is the relationship between temperature and vapor pressure?

The relationship between temperature and vapor pressure is based on the fact that as temperature increases, the kinetic energy of the molecules in a substance also increases. This heightened kinetic energy enables more molecules to escape from the liquid phase into the vapor phase, which in turn raises the vapor pressure. Essentially, a higher temperature allows a greater number of molecules to enter the vapor state, leading to an increase in vapor pressure.

Understanding this relationship is crucial in the context of drying processes, where controlling the temperature can significantly influence the efficiency of moisture removal from materials. For example, in commercial drying applications, operators often increase the temperature to elevate vapor pressure, thereby enhancing the moisture removal rate from affected structures or materials.
