The Nature of fire

Description

A fire needs heat, fuel, and oxygen. This Science Screen Report examines that triangle of ingredients, and how scientists study it in order to combat-or harness-fire. With detailed examples of firefighting techniques, the program demonstrates the removal of heat from a class A blaze through the use of water or sprayed polymers, and the elimination of oxygen, a strategy used in fighting oil fires. The video concludes with a focus on the internal combustion engine and the oxyacetylene torch, two technological achievements that transform fire into a tool.
