Substances with high vapor pressure are generally:

Substances with high vapor pressure are more likely to evaporate because vapor pressure is a measure of a substance's tendency to transition from a liquid to a gas. When a substance has a high vapor pressure, it indicates that a significant number of its molecules have enough energy to escape into the vapor phase. This property is a direct reflection of the substance's volatility; higher volatility means a greater propensity for evaporation.

In practical terms, this means that substances with high vapor pressure can easily transition into the air, contributing to the formation of vapors that may pose hazards, especially in the context of hazardous materials handling. For instance, if a chemical in a storage container has a high vapor pressure, there is an increased risk of harmful vapors being released into the environment, making it essential for hazmat technicians to be aware of these characteristics when planning safe handling and storage procedures.
