Gas propellants in a can are typically used in products like aerosol sprays to push out the contents when the nozzle is depressed. They are mixed with the product and create pressure to allow for the product to be sprayed out in a fine mist or stream. It's important to handle these cans carefully and follow safety instructions, as they can be flammable and hazardous if used improperly.

The ideal gas law is typically applied in a spray can. This law describes the relationship between pressure, volume, and temperature of a gas. When the propellant gas inside the spray can is compressed, it increases the pressure, allowing the contents to be released when the nozzle is pressed.
Aerosol spray cans contain a propellant gas, liquid product, and a valve system. When the nozzle is pressed, the valve opens, allowing the propellant to force the liquid product out of the can as a fine mist or spray. The propellant evaporates quickly, leaving the product suspended in the air.
The typical gas used as a propellant in aerosol solvent based paint cans is Propane, Chemical Abstract Number 74-98-6. The propellant used will depend on the contents of the can, as it must be a chemical that is compatible with the contents. Most liquids can be put into an aerosol can. The liquid is placed into the can, the liquid is diluted to make it thin enough to spray through the nozzel of the spray can and then a compressed gas propellant is added to expel the contents of the container in the form of an aerosol.
The propellant used in whipped cream is nitrous oxide, also known as laughing gas.

R-22 is a colorless gas that is used as a propellant and refrigerant. The technical name for this gas is chlorodifluoromethane.

When the aerosol can's nozzle is pressed, it opens a valve that releases the pressurized gas propellant. The propellant pushes the product in the can (such as spray paint or deodorant) out through the nozzle. The force of the gas escaping propels the product forward in a fine mist or spray.
Whe the propelant gas is released from the can the equilibrium gas-liquid is disrupted and more liquid is evaporated.
