Answer:

Image result for definition and characteristics of fire, flame and combustion.​

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. ... At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.

The zone of burning gases and fine suspended matter associated with rapid combustion; a hot, glowing mass of burning gas or vapor. noun The condition of active, blazing combustion. noun Something resembling a flame in motion, brilliance, intensity, or shape. noun A violent or intense passion.

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Answer 2

Combustion is an exothermic reaction, so it releases heat, but sometimes the reaction proceeds so slowly that a temperature change is not noticeable. Good signs that you are dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products.

Fire is Fast. There is little time! ...Fire is Hot. Heat is more threatening than flames. ...Fire is Dark. Fire isn't bright, it's pitch black. ...Fire is Deadly. Smoke and toxic gases kill more people than flames do. ...Escape First. ...Smoke Alarms.

Characteristics of Flame

flame consists of a narrow plume of pale blue flame. A flame that contains any tint of orange color means that either not enough gas is flowing through the burner or not enough air is being mixed with the gas. An orange flame will not be hot enough for most laboratory purposes
