Question

What are the four components required to make fire possible?

A. Oxygen, wood, plastic, and a chemical chain reaction
B. Fuel, heat, sparks, and a fire tetrahedron
C. Ignition, oxygen, air, and contact with a heat source
D. Oxygen, heat, fuel, and a chemical chain reaction

Answer 1

D

Step-by-step explanation:

To create fire, a fuel source, oxygen, O2 (abundant in the air), and chemical chain reaction must occur in order to convert the fuel source into its products (typically H2O and CO2 in organic combustion).

Answer 2

The four components required to make fire possible are oxygen, heat, fuel, and a chemical chain reaction.

Step-by-step explanation:

In order to make fire possible, four components are required: oxygen, heat, fuel, and a chemical chain reaction. Oxygen supports the chemical processes that occur during the fire and is necessary for combustion. Heat is responsible for the ignition and spread of fire. Fuel, which can be any combustible material, provides the substance that undergoes the chemical reaction. Finally, a chemical chain reaction occurs when the fuel reacts with oxygen, releasing heat and generating combustion products.
