The propellant, coupled with the special spray nozzle, spreads a small amount of liquid throughout a much larger amount of the gas also contained in the can. The can is spraying both liquid AND gas.

How have aerols affected the ozone layer?
Aerosol spray cans contain CFC's. There are hard ODS.
How do aerosol spray cans work?
It would be quite spectacular I think. The vacuum would cause the can to explode.
Who invented aerosol spray cans?
Erik Rotheim
Do aerosol spray cans have to be in a cabinet?
They don't have to be in a cabinet. Some people store there aerosol cans in hollowed out TV sets and some people bury them in the ground in treasure chests. I keep my aerosol spray cans in a locked box hidden in my attic, so they will never be stolen.
What is the value chain of Aerosol cans?
The value chain of aerosol cans is all about supply and demand. Aerosol cans are necessary for most jobs that require spray paint, or cleaning supplies. The value will depend on what product is being used in the cans.
Is water repellent aerosol spray that says it does not contain ozone depleting CFCs more likely to be a Class 1 or 2 ODS and is it Virgin or Used?
Aerosols contain CFC's. They are used as spray cans and deplete ozone.
What is the gas in aerosol cans?
The aerosol-can uses compressed gas as a propellant.Since the product is liquid at room temperature, it is simply poured in before the can is sealed. The propellant, on the other hand, must be pumped in under high pressure after the can is sealed. When the propellent is kept under high enough pressure, it doesn't have any room to expand into a gas. It stays in liquid form.When the button is pressed the pressurized gas pushes the liquid product, as well as some of the liquid propellant, up the tube to the nozzle. Some cans, such as spray-paint cans, have a ball bearing inside. If you shake the can, the rattling ball bearing helps to mix up the propellant and the product, so the product is pushed out in a fine mist.Up until the 1980s, a lot of liquefied-gas aerosol cans used chlorofluorocarbons (CFCs) as a propellant. After scientists concluded that CFCs were harmful to the ozone layer, 70 nations signed the Montreal Protocol, an agreement to phase out CFC use over the next decade. Today, almost all aerosol cans contain alternative propellants, such as liquefied petroleum gas, which do not pose as serious a threat to the environment.
Who invented aerosol sprays?
Aerosol spray cans were invented by Lyle David Goodloe and W. N. Sullivan in 1941.
What job did Erik Rotheim hold?
He was a chemical engineer that invented aerosol spray cans.
Are air horns allowed on planes?
according to the TSA policy, no aerosol cans are allowed. It doesn't specifically say airhorns but it should be implied. i.e. spray cans, lighter fluid cans, hair spray cans.
Where can you find chlorofluorocarbons?
Shaving Cream Fire extinguishers Chlorine (like in swimming pools) Aerosol Cleaning Solvents Some types of Wall Insulation Fast-Food Cartons Old Air Conditioners, and some new ones Old Refrigerators Automobile Heaters and Coolers Electrical Equipment (such as wiring)
Why are volatile liquids often used in aerosol spray cans?
What kind of liquids are you talking about? ... and why do you mean volatile? Do you mean flammable? The question refers to the propellants used in aerosol spray cans. If aerosol cans were filled with compressed gas, they would have to be designed to withstand extremely high pressures, which would not be cost-effective. Instead, liquid propellants (usually butane, isobutane or propane) are used, which allow a much larger amount of propellant to be stored, at a reasonable pressure. These liquid propellants are "volatile" in the sense that a small amount of the liquid evaporates every time some of the gas is released, so that the vapor and liquid stay in equilibrium. As it happens, most of these liquid propellants are also flammable, but the term "volatile" refers to their tendency to evaporate.
