Hot water extinguishes fire faster, as the heat that must be absorbed to convert hot water to steam is much greater than the heat …
So, boiling water is even better than Hot water for extinguishing the fire. Hence boiling water can extinguish fire more quickly than hot water, ice or cold water. So, option B is the correct option. Note- The condition required to start a fire is well known as “fire triangle,” in which three things are necessary to create and sustain fire.
Hot Water or Cold Water: Which Extinguishes Fire Faster?
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 […]
Although it is true that technically cold water will put out a fire faster than hot water, most of the cooling effect comes from changing the water into steam, not from raising the temperature of the water. In fact there’s less than a 1% advantage in using cold water.

How does water extinguish a fire?
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. This cooling occurs due to the heat being absorbed by liquid water to transform itself into vapor (more on this later).
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.
Does removing fuel instantly extinguish a fire?
However, removing fuel doesn’t instantly extinguish a fire, but rather restricts its further dispersal. Lastly, fire needs oxygen to breathe and continue its onslaught. Without a steady supply of oxygen, a fire starts to simmer down and ultimately dies.
What happens when you spray water on a fire?
Upon being sprayed, water first has a cooling effect on the fire. This cooling occurs due to the heat being absorbed by liquid water to transform itself into vapor (more on this later). Also, once liquid water is converted into vapor, it establishes a barrier between the burning fuel and atmospheric oxygen.
