broader: variable matrix
definition: Comprised of liquid or solid particles, or of liquid particles with a solid core, or of bulk solid material, where the particles are suspended in a gas. The aerosol particle phase excludes the carrier gas. In liquids, molecules flow easily around each other but are held together by attractive forces. In solids, molecules are arranged in a regular pattern, firmly held in place and only able to vibrate within a limited space.
