Can you guess why fire extinguishers throw a stream of carbon-di-oxide while putting – off fire?

Answer»

The reasons behind fire extinguishers throw a stream of CO, while putting-off fire:-

1. CO2 is a colourless and in normal concentrations, odourless gas. It doesn’t react with burning materials, so it doesn’t create any toxic or other by products while putting-off fire. 

2. Carbon dioxide doesn’t conduct electricity, making it an ideal fire suppressant for use in the places where a large amount of electricity may be present. 

3. CO2 acts on fires in two ways: The release of the gas under pressure has a cooling effect, as can be seen by the resulting mist cloud and ice particles; the gas also displaces the oxygen that’s necessary to maintain combustion
