Panchatattva has great importance in our life. Life cannot be imagined without them. It includes sky, air, fire, water and earth. It is said that from this the soul and body originate. But today we will talk about one of these five elements, fire. Let us tell you that fire is an element which has no shape. But have you ever wondered why the colors of fire are different?
What is fire after all?
According to science, fire is a process which produces both heat and light. Apart from that, the effect of chemical reactions is called fire. The process of burning or combustion takes place in this. However, its reactions require the presence of oxygen, a burning substance and a certain temperature.
explosive substance
Let us tell you that things that can burn with fire are called inflammable substances. But some things catch fire so quickly that they explode. Such things are called explosive substances. In these also the explosion gas is controlled and used. For example, the gas that is burnt for cooking in the kitchen is an example of this. At the same time, gunpowder causes uncontrolled explosion even with the slightest spark.
Let us tell you that every substance can be burnt. But under normal circumstances, only water-soluble substances are used as fuel. The heat released after burning of this substance is used in many types of works. For example, earlier train engines used to run on coal. During that time, after burning of coal, engines were run on the heat of coal. However, according to science, anything needs oxygen to burn.
