How does a fire extinguisher works ?​

Chemistry
1 answer:
Usimov [2.4K]1 year ago
8 0

Answer:

<em>Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go </em><em>out.</em><em> </em><em>S</em><em>ome </em><em>ways </em><em>of </em><em>using </em><em>fire </em><em>extinguisher </em><em>are:</em>

  • <em> Water extinguishers work mainly by cooling (removing heat), but a dense spray of water droplets also helps to cut off oxygen. </em>

  • <em> Dry powder extinguishers soak up heat, melt on the fuel, and cut off oxygen, but they also neutralize the </em><em>fuel</em><em> (cutting it off from the </em><em>fire)</em><em> </em><em>.</em>

Explanation:

Agglutination (clumping) will occur when blood that contains the particular antigen is mixed with the particular antibody.

A+ have Agglutination with Anti-A ,Anti-Rh and No agglutination with Anti-B.

A- have Agglutination with Anti-A and No agglutination with Anti-B and Anti-Rh.

B+ have Agglutination with Anti-B Anti-Rh and No agglutination with Anti-A.

B- have Agglutination with Anti-B and No agglutination with Anti-B and Anti-Rh.

Rh+ have Agglutination with Anti-A and Anti-Rh and No agglutination with Anti-B.

Rh- have No Agglutination with Anti-A and Anti-B and Anti-Rh.
