Aerosol is made of tiny solid particles or liquid droplets that are suspended in a gas, usually air.For example:• In spray cans (like deodorant or paint), an aerosol has liquid mixed with a propellant gas that pushes it out as a fine mist or spray.• Natural aerosols include dust, smoke, mist, and sea salt particles floating in the air.So, an aerosol = small particles (solid or liquid) + gas carrier (air or propellant).
