Question

2.
The combustion which takes place in adequate
amount of air or oxygen
3. A region where combustion of fuel takes place
4. Flame that emits a lot of light
5. The amount of heat produced in kilojoules when onegram of fuel is completely burned
6. The resources which have limitless supply
actions​

Answer 1

1. Complete combustion
2. flame
3. A luminous flame is a burning flame which is brightly visible. Much of its output is in the form of visible light, as well as heat or light in the non-visible wavelengths.
4. Calorific value is the quantity of heat produced by the complete combustion of a given mass of a fuel, usually expressed in joules per kilogram. It can be defined as the amount of heat energy produced on complete combustion of 1 Kg of fuel.
5. Renewable resources are natural resources that can be replaced in a relatively short period of time or are virtually limitless in supply. In addition to wind, renewable energy resources include sunlight, moving water, biomass, and geothermal energy. All of these resources are freely available and won't run out.
