Question

In which state of matter does fire exist?

Answer 1

Hint: We have to know that the states of matter are mainly divided into three types and that is, solid, liquid, gas and plasma. And each matters have different chemical and physical properties. In solids, all the particles are arranged very closely. Hence, the force of attraction present between the particles is very strong and it cannot be moved and it has a definite shape. And in the case of liquids, the distance between particles is greater than solid and its shape is depends upon the container. The gas does not have any perfect size or shape. And the plasma is superheated matter.

Complete answer:
We have to remember that the fire is formed by the rapid oxidation of any substance undergoing the exothermic reaction and it is a chemical process of combustion. By the formation of fire, there is a release of light, heat and different reaction products. And the flame released by the fire contains water vapour, carbon dioxide, nitrogen and oxygen.
The fire exists in a plasma state of matter. Because, the fire does not convert into the liquid state. Because it does not have any definite volume. And the fire will not fall into the solid. Because it does not have a particular shape.

Note:
As we know that the fire exists in the plasma state, and it contains a huge amount of kinetic energy. The number of protons and the electrons are equal in the plasma state and here the hot ionized gases are compressed. Hence, if hot enough, the gas will ionize and there is a formation of plasma. The colour of the flame will be different according to the impurities present in the samples.
