Hot water extinguishes fire faster, as the heat that must be absorbed to convert hot water to steam is much greater than the heat …
The answer is- Hot water. Hot water extinguishes fire faster as compared to cold water. Explanation: How fire Occurs? Fire is actually an event rather than a thing. Typically, fire occurs from a chemical reaction in presence and right combination of its three elements: heat, fuel, and an oxidizing agent (usually oxygen). To eliminate fire […]
Which extinguishes fire more quickly, hot or cold water?
Answer (1 of 9): To sustain fire you need three things: fuel, heat and oxygen.Taking cold water means it will raise its temperature say from 20°C to 100°C which requires heat energy of 80 calories per gm and then change its state which requires 540 calories per …
The process of fire extinguishing involves absorption of heat. Absorption of heat in converting hot water to steam is more than heat absorbed in heating cold water to the boiling temperature. Hence, hot water extinguishes fire more quickly than cold water.

Does hot water or cold water extinguish fire faster?
Hot water extinguishes fire faster, as the heat that must be absorbed to convert hot water to steam is much greater than the heat absorbed in bringing cold water up to 100°c. “A fire seems to have started outside!! Quick, get me some water!”
How does water extinguish a fire without oxygen?
Without a steady supply of oxygen, a fire starts to simmer down and ultimately dies. Water extinguishes a fire by simultaneously severing two of its heads—heat and the oxidizing agent. Upon being sprayed, water first has a cooling effect on the fire.
Can we use water to extinguish a flame?
(Q dot.) So yes of course applied directly to the area of a class a fuel you would have a decisive effect and extinguish the flame- but from the perspective of cooling a confined area like a room in a house you’d still have an impact but less decisive than if we were using cooler water.
Why is water so effective at putting out fires?
Water is more effective than most other liquids at putting out fires due to its chemical properties, specifically its heat capacity and latent heat of vaporization. Heat capacity is the amount of heat required to raise the temperature by one Kelvin. Water has one of the highest specific heats among other naturally occurring substances.
