“Whether it’s hot or cold water, what difference does it make?” You can think of it as: However, the temperature of the water makes a significant difference in extinguishing the fire.

So which one is correct?

First, let’s see how water puts out fire.

When water is sprayed on a fire, it first has a cooling effect. This cooling It is created when liquid water absorbs heat and turns into steam. Additionally, when water is converted into steam, it creates a barrier between the burning fuel and the oxygen in the air.

This interrupts the supply of oxidizing agent. That’s exactly how a fire extinguisher worksWhen CO2 is released under pressure from a fire extinguisher, the resulting CO2 cloud interrupts the oxygen supply to the fire and eventually extinguishes the fire.

Hot water will put out fire faster than cold water.

Because cold water has trouble reaching boiling point at first. Because the temperature of hot water is already close to boiling point, It takes less time to reach 100°C.

For this reason, the high latent heat of vaporization of water, It activates earlier for hot water than for cold water. This means that the heat is absorbed more quickly by the warm water.

In addition, faster conversion to steam, faster formation of a barrier between the burning fuel and oxygen resources.

In summary: higher heat absorption and faster barrier formation when changing into steam, It helps hot water extinguish the fire faster than cold water.
