The term 'FINE SPRAY' can be broken down into two crossword solutions: AEROSOL (7 letters) and MIST (4 letters). An AEROSOL is a type of container that dispenses a product in the form of a spray, foam, or gas. It is usually made of metal or plastic and contains a propellant such as compressed air or a volatile hydrocarbon. A MIST is a fine spray of liquid droplets suspended in the air. It is created when a liquid is forced through a nozzle or other device, creating a fine spray of tiny droplets. Both aerosols and mists are used to disperse liquids in a fine spray, making them ideal for applications such as cleaning, cooling, and coating.
