Fire Behavior

Anything that occupies space and has mass

Heat producing chemical reaction between some type of fuel and oxygen that burns, heat is generated faster than it can be dissipated and increases in temperature.

Occurs when a substance remains chemically the same but changes in size, shape, or appearance

Occurs when a substance changes from one type of matter into another

Is a chemical reaction involving the combination of oxygen

Metal to rust

21%

Chemical reaction between two or more materials that changes the materials and produces heat, flames , and toxic smoke

Chemical reaction in which a substance absorbs heat energy

An Exothermic chemical reaction that is a self sub staining process of rapid oxidation of a fuel that produces heat and light Fire is an example

Oxidation involves fuel in the gas phase Heat of both liquid and solid fuels will give off vapors that mix with oxygen and can burn producing flames

Under oxidation at the surface that char but no flame is present Example charcoal

Oxygen Heat Fuel

Oxygen Heat Fuel Self sustained chemical chain reaction

Is a source of energy that exists in two states potential and kinetic

Stored energy possessed by an object that can be released in the future to perform work

The energy possessed by a moving object Chemical energy is converted into kinetic energy in the form of heat and light.

Is the measurement of kinetic energy

Is the amount of heat required to raise the temperature of 1 pound of water 1 degree Fahrenheit

Celsius- metric system Fahrenheit - customary system

The chemical decomposition of a substance through the action if heat. Solid to vapor form during the burning process

Liquid to vapor form

Piloted ignition Auto ignition

Occurs when a mixture of a fuel and oxygen encounters an external heat source that starts combustion
