Volatile organic compounds (VOCs) are organic chemicals characterized by their high vapor pressure at room temperature, which enables them to easily vaporize and enter the air. This property is significant because it highlights their potential for affecting air quality and contributing to various environmental issues, including smog formation and health risks upon inhalation.

In many applications, particularly in industrial and consumer products such as paints, solvents, and cleaning agents, the high volatility of these compounds is a critical factor. It allows them to disperse rapidly in the atmosphere but also poses challenges for air quality management due to their ability to react with other pollutants, leading to secondary pollution problems.

Understanding that VOCs have a tendency to evaporate easily at normal temperatures helps in identifying their sources and potential impacts on human health and the environment, making the correct choice insightful regarding their characteristics and behaviors.
