Concept Introduction :
The power or capacity to perform work, for example: the capability to move an object by applying the force is known as energy.
Answer to Problem 4E
Three ways in which fire is central to life are:
- Used as oxidation material in the exothermic chemical process of combustion.
- Used as Fuel
- Used for Cooking
Explanation of Solution
In the
Below are the three ways which fire is central to life in our planet:
- Used as oxidation material in the exothermic chemical process of combustion
- Fire is used as a fast oxidation material within the exothermic chemical reaction which releases light, heat and numerous reactants.
- Used as Fuel
- Usable energy is released when fuel is aflame. Wood, coal is a fuel when they are burned; they release the energy which are used in various purposes. Like coal, natural gas, petroleum is used to supply majority of electricity in today’s world.
- Used for Cooking
- Fire is used by humans to properly cook the foods, instantaneously increasing the availability and variety of nutrients as well as decreasing the disease by eliminating organisms from the food.
