What occurs during volatilization?

During volatilization, a solid or liquid transforms into a gas through a process that involves the addition of energy, often in the form of heat. This transition can be observed when substances such as water move from a liquid state to a gaseous state (water vapor) as it is heated. Similarly, some solids can also undergo volatilization when they reach their boiling point or sublimation point, turning directly into gas without becoming a liquid first. This process is significant in various applications, including wood preservation, where the active chemicals may need to volatilize to penetrate the wood effectively or to disperse in the environment. Understanding how materials transition into gas form helps in comprehending and managing the usage and application of preservatives in wood treatment processes.
