Question

List conditions under which combustion can take place.

Answer 1

Hint:Combustion is a chemical process, or we can say the process of burning a substance. This process represents an exothermic, and redox chemical reaction. Now, we can identify the conditions under which combustion takes place.

Complete step by step solution:
> First, let us define the combustion. As mentioned it is a chemical process of burning a substance. It is also known as burning.
> This reaction occurs between the reductant, and an oxidant; and there is formation of gaseous products.
> As we know, it is necessary that the combustion process will show a fire, but if it happens, the indicator of this reaction is a flame.
> So, the reductant in the combustion process is a fuel, and the atmospheric oxygen acts as an oxidant. This is the reason that products are oxidized.
> We have one other factor that is the ignition temperature, it must be maintained as it is defined as the minimum temperature at which the substance catches fire.
> Thus, in the last we can say that the conditions required for the combustion are the presence of air, or oxygen, and the presence of a fuel, and ignition temperature must be maintained.
So, there are three conditions as discussed required for the combustion to take place.

Note: The maintenance of ignition temperature is must because it represents the basic property of a fuel, and when it reacts with the oxygen in air; it should be lower to prevent excess burning.
