Answer 2

Answer:

here it is

Explanation:

CO2 can be used as a fire extinguisher in the following two ways

1. it can be used in fire extinguisher to stop the fire the molecules of CO2 are more heavier than O2 molecules and cover up the material or fuel which is burning and thus cut off the supply of oxygen.
2. CO2 gas molecules are cooler if they are compressed and in fire extinguisher it is in compressed form and thus when released it cools down the temperature of the fuel and make it below it ignition temperature and thus the fire gets off.
