When C O 2 under high pressure is released from a fire extinguisher particles of solid C despite the low sublimation temperature it is t he gas does work pushing back the atmosphere using KE of molecules and thus temperature. This is stored in the extinguisher as a liquid and the gas is created under pressure when the handle of the extinguisher is squeezed.

The pressure inside the cylinder on top of the extinguishing agent pushes the extinguishing agent out through the dip tube through the fire extinguisher head and into the.
