It contains gases that give me carbon dioxide, foam or any other gases
Answer 2 
Density is defined by the unit volume of the substance . Hence it tells us how closely the molecules are packed. The greater the density the more closely the molecules are packed. If the object is denser than the water it will sink and if the object is less denser than the water it will float in the water.

Fire extinguisher is a device that is used to put out fire . It ussaly contains chemicals that give me carbon dioxide, foam or any other gases that are helpful to put out the fire.
