It turns out that ordinary water from the tap can easily set fire to various objects (matches, paper, sparklers, etc.). Think a joke? And no! This can easily be verified if you conduct a small experiment.
To do this, pour ordinary tap water into a small glass flask. In the upper part, the flask is closed with a rubber plug (stopper), through which a copper tube passes through, twisted in the middle into rings.
Bit of theory
To get fire, you need three main components: heat, fuel and oxygen. It is a known fact that water has a high heat capacity. In other words, water conducts heat very well and quickly takes it away from other objects with which it comes into contact. Therefore, when water is flooded with fire, it naturally dies out.
In the surrounding nature, heat always transfers from a warmer object to a less heated one. From this rule, we can conclude that if the water is heated above the ignition temperature of the material, the liquid will itself give off heat, and not take it.
The main stages of the experiment
First of all, you need to heat the water in a glass flask to a boil - and for this you can use a piece of dry alcohol. When the water boils, you need to heat it above the ignition temperature of the material.
To do this, we heat the coil on the copper tube with a gas burner. Thus, we get superheated steam, which will be able to ignite flammable materials (paper, matches, etc.).
By changing the direction of the temperature gradient, fire can be obtained from water.
