Sample Question
Electrical fires cannot be safely put out by dousing them with water. However, fire extinguishers spray solid carbon dioxide on the firework very effectively. This method works because of carbon dioxide:

Displaces the oxygen.

Renders the fire’s fuel non-flammable.

Forms water vapor.

Blows the fire out with strong wind currents.
