Prescribed fire characteristics can be defined as the effects of flaming that cause a degree of impact on the plant communities. Fire characteristics include flame height, fire intensity, season, frequency, flame angle, flame depth and scorch height.

The color of a fire is a rough gauge of how hot it is. Deep red fire is about 600-800° Celsius (1112-1800° Fahrenheit), orange-yellow is around 1100° Celsius (2012° Fahrenheit), and a white flame is hotter still, ranging from 1300-1500 Celsius (2400-2700° Fahrenheit).

In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases ...

There are actually five main types of fires. Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach.

As nouns the difference between combustion and fire is that combustion is (chemistry) the act or process of burning while fire is (uncountable) a (usually self-sustaining) chemical reaction involving the bonding of oxygen with carbon or other fuel, with the production of heat and the presence of flame or smouldering.

Generally speaking, fire signs are passionate and exuberant, earth signs are practical and grounded, air signs are intellectual and curious, and water signs are intuitive and emotional. Quadruplicities are the signs' qualities.

A fire requires fuel to burn, air to supply oxygen, and a heat source to bring the fuel up to ignition temperature. Heat, oxygen and fuel form the fire triangle. Firefighters often talk about the fire triangle when they are trying to put out a blaze.

Fire is combustion of a gas, the Sun is a ball of nuclear fusion (no actual "burning"). Fire is not very dense (s.g. = . 01 g/cc) vs the sun is very dense, even denser than lead (s.g. = 160x denser than water). Fire is 1000 to 3000 degrees F.

Fire is made up of many different substances, so it is not an element. For the most part, fire is a mixture of hot gases. ... If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma. Burning a metal, such as magnesium, can ionize the atoms and form plasma.

The important chemical properties of organic compounds are Combustion: Carbon in all its allotropic forms burns in air or oxygen to give carbon dioxide and releases energy in the form of heat and light. Most carbon compound also release a large amount of heat and light on burning.

Ignition temperature is the lowest temperature at which a combustible substance when heated (as in a bath of molten metal) takes fire in air and continues to burn. Fire point is the lowest temperature where the vapor of a liquid will initiate and sustain a combustion reaction .
