Fire extinguishers contain various compounds, depending on the type, that work by interrupting the chemical reactions that sustain fire. The most common compounds used are carbon dioxide (CO₂), monoammonium phosphate, and sodium bicarbonate.
Common Compounds in Fire Extinguishers:
- Carbon Dioxide (CO₂):
- Used in CO₂ fire extinguishers, it works by displacing oxygen around the fire. CO₂ is non-flammable and suffocates the fire by reducing the oxygen supply, which is essential for combustion.
- Monoammonium Phosphate:
- Found in ABC dry chemical fire extinguishers, this compound works by coating the fuel and preventing the chemical reactions occurring at the fire’s surface. It is effective for electrical, grease, and other general fires.
- Sodium Bicarbonate (Baking Soda):
- Present in some dry chemical extinguishers, it works by releasing carbon dioxide when heated, which helps smother the fire. It is commonly used for Class B (liquid) and Class C (electrical) fires.
Working of a Fire Extinguisher:
A fire extinguisher works by applying a substance that either cools the fire, displaces oxygen, or inhibits the chemical reactions of combustion.
- CO₂ extinguishers are effective for electrical fires and flammable liquids, as they do not leave residue.
- Dry chemical extinguishers (using monoammonium phosphate) work on a wide range of fires (A, B, C) by coating the fuel and interrupting the fire’s chemical reaction.
By removing one or more of the elements in the fire triangle (heat, fuel, oxygen), the fire is extinguished.

Classical computing relies on binary bits (0s and 1s) to process and store information, following well-defined algorithms that execute sequentially. Quantum computing, however, uses quantum bits or qubits, which can exist in superposition (both 0 and 1 simultaneously) and entanglement (where the state of one qubit is dependent on the state of another), allowing quantum computers to perform complex computations in parallel.
Quantum computing has the potential to revolutionize fields like cryptography and material science:
1. **Cryptography**: Quantum computers could break many of the widely-used cryptographic algorithms (such as RSA and ECC) due to their ability to perform calculations exponentially faster than classical computers using Shor’s algorithm. This could render current data encryption methods obsolete, prompting the need for new quantum-resistant cryptographic algorithms.
2. **Material Science**: Quantum computers can simulate quantum systems accurately, which is challenging for classical computers due to the computational resources required. This capability could lead to discoveries of new materials with specific properties, revolutionizing fields like drug discovery, energy storage, and materials design.
In summary, while classical computing operates linearly with binary bits, quantum computing leverages quantum mechanics to potentially solve complex problems exponentially faster. This difference could profoundly impact fields reliant on computational power, particularly cryptography and material science, by enabling faster calculations and simulations beyond the capabilities of classical computers.
