Which term describes small particles that remain suspended in a gas or liquid?

Aerosols are defined as small particles or droplets that are suspended in a gas or liquid. This can include a variety of substances, such as spray particles in the air or mist in a liquid. The particles in aerosols can be solid or liquid and are usually small enough to remain suspended for an extended period, which allows them to disperse throughout the medium in which they are contained. This term is widely used in various fields, including chemistry, environmental science, and health, as it encompasses phenomena such as air pollution, respiratory health, and the delivery of certain medications through inhalers.

Fumes typically refer to gases or vapors that are emitted during combustion or thermal decomposition and are often associated with high-temperature processes. They are not particles suspended in a medium but rather products of the reaction.

Vapors are defined as the gaseous state of a substance that is normally liquid or solid at room temperature. While vapors can be part of an aerosol, they do not describe the particulate component that is suspended.

Emulsions refer to mixtures of two immiscible liquids, where one liquid contains a dispersion of the other. This term does not apply to particles suspended in gases or liquids in a general sense, but rather to specific types of liquid
