Using at least 3 to 4 complete content related sentences, explain how the compressed gas in an aerosol can forces paint out of the can?
The can contains a gas propellant under high pressure.
When you push the button and open the valve, the pressure forces the paint up the tube and out through the nozzle.
The narrow nozzle breaks the flowing paint into tiny drops, which disperse as a fine spray.
As the paint gets used up, it makes more room for the gas.
When the gas expands, its pressure decreases (Boyle's Law).
So, the more paint that is sprayed out, the less the pressure in the can.
