Why are fire extinguishers cold

The majority of fire extinguishers will still function adequately after being stored in freezing temperatures. However, for safety reasons, you must replace devices that are damaged. Storing fire extinguishers outdoors in normal or freezing temperatures leaves them open to …

Two reasons: Gas gets warm as it is compressed (SCUBA tanks are routinely in a water bath as they get filled). Then, over time it cools to the ambient temperature. Carbon Dioxide has a very high thermal capacity, that is, they get VERY hot as they are filled. When the extinguisher is discharged, the gas is very cold.

Why Does the Horn of the Carbon Dioxide Fire Extinguisher Become Cold? | eHow 2) Also there will be some temperature drop because CO2 is not an "ideal gas". There are forces between the molecules. As the gas expands, CO2 molecules will lose kinetic energy as they move apart against attractive intermolecular forces.

Does CO2 come out of a fire extinguisher hot or cold?

although CO2’s heat of vaporization is only 151J/g at room temperature, far less than water). So… that’s the long way of saying every other answer is correct: CO2 from a fire extinguisher comes out very cold, cold enough to form dry ice and give you cold burns. EDIT: Thanks to David Talaga for correction.

Why does a fire extinguisher hose freeze up?

In the case of the extinguisher, the temperature falls far below the freezing point of water and the humidity in the air condenses on the hose and can even freeze forming a layer of frost. Why does a CO2 fire extinguisher hose get ice old when used?

What happens if you add more oxygen to a fire extinguisher?

Adding more oxygen would just cause the fire to grow to a rather large size. The co2 replaces the oxygen thus extinguishing the fire. Carbon dioxide is a good fire extinguisher but when we blow air from our mouth to the fire which contains carbon dioxide it intensifies.

How does a fire extinguisher work?

The air and diesel fuel are compressedly the piston so much that the diesel fuel ignites. The opposite situation occurs when a pressurized gas has the pressure released and the temperature falls. In the case of the extinguisher, the temperature falls far below the freezing point of water and the humidit
