Why does a fire extinguisher form solid CO2 when it is activated?

The reduced pressure causes the liquid CO2 in the extinguisher to boil. This lowers the temperature and some is converted into a solid. This can be used to make small quantities of dry ice in the lab.

Do I have to take a fire extinguisher class?

How do you make dry ice without fire extinguisher?
A fire extinguisher does no make dry ice. Dry Ice is the solid form of the gas Carbon Dioxide. At room temperature is you compress (and cool) CO", it turns into solid CO2 (dry ice) without forming a liquid phase.
Is hydrogen inside a fire extinguisher?
Not in elemental form. Hydrogen is highly flammable, so putting it in a fire extinguisher would be a very bad idea. Some fire extinguishes contain water, which is a compound of hydrogen and oxygen.
Why carbon dioxide in a fire extinguisher turns into a liquid?
It does not. Technical input: compressed CO2 might be in liquid form INSIDE the fire extinguisher because it is under more than about 5 atmospheres of pressure.
What will happen if you remove syphon tube from the CO2 fire extinguisher?
If you remove the siphon tube from a CO2 fire extinguisher, the extinguisher will not work properly. The siphon tube is responsible for drawing and releasing the CO2 gas from the extinguisher. Without it, the CO2 gas will not be able to flow out effectively, rendering the extinguisher ineffective in suppressing fires.
Fire is which form of mater?
Fire, before you think differently, is a form of matter. Everything is. Fire itself is in the gas state. Some people think it is a solid, but in fact it does not have the substances that make it solid (or liquid for that matter).
Is fire a solid?
Fire is not a state of matter as the examples you gave. Fire is a reaction. It consumes matter, changing the solid to it's components of ash(solid), water vapor(gas), and heat.
What solid wont melt in a fire?
Any solid whose melting point is lower than that of the fire. The question is ambiguous because the temperature of the fire it not stated. The sun is form of a fire but its surface temperature is several million Kelvins, nothing including steel is solid at that temperature. A candle light is around 900 degrees steel is solid at this temperature.
How do you put an electric fire out?
First priority is to remove the source of the electricity. Without that, the fire will continue to form. After disconnecting the electrical source, put out the fire as normal, with a co2 extinguisher and foam. Sand works too.Improvement:Sand is the best option after a CO2 extinguisher. Improvement:I agree but you could also try smothering it with a fire blanket (if you don't have a CO2 extinguisher lying around!) to take away the oxygen BUT NEVER put water on an electrical fire it just makes it worse.IMPROVEMENT;here are some good tips,NEVER USE WATERif it is small you could use some baking sodaan ABC or class C fire extinguisher are best
What does a dry chemical fire extinguisher do?
A dry chemical fire extinguisher is a fire extinguisher that disburses a dry chemical agent to actively suppress a fire. The agent will smother the fire (cut off oxygen) and halt the chemistry (free radical production) of a small blaze. Compressed nitrogen is the most common propellant for the powder. The powder used in the device can be any one of several different chemicals, and the ones we commonly see include ammonium phosphate, sodium bicarbonate, and potassium bicarbonate, or a combination of them and another ingredient. The type of chemical will determine its rating (class A, B and/or C fires), and the chemical properties of the agent will determine its effectiveness on a given fire type and what can be expected in cleaning up after the fire. A link is included below so you can check facts and gather additional information.
Why would frost form on the outside of a fire extinguisher?
When looking at this use the equation PV = nRT. From this you can see that temperature and pressure are proportional to one another. So if your temperature increases for the same volume and number of moles your pressure must also increase. When you use a fire extinguisher you rapidly decrease the pressure inside the container which causes the temperature to decrease. The frost you see is water vapor from the air freezing when it comes into contact with the cold outside of the extinguisher.
Is organic salt a form of extinguisher?
Yes, some types of Class D fire extinguishers use NaCl (table salt) as an extinguishing agent for fires involving magnesium, sodium and potassium.
