Fire is a combination of chemical and physical changes in which substances interact to release heat, light, smoke and ash. Whether it is a fire in electrical insulation, an oil fire or a simple domestic fire, they all require three ingredients - combustible material, oxygen and a thermal trigger.
If one of these is absent, the fire goes out. This principle is the basis of fire-fighting, which aims to cool the flames by smothering them, removing oxygen, or depriving them of fuel.
Combustible material often consists mainly of carbon and hydrogen and can be almost anything solid, liquid or gaseous, from hydrogen to wax, oil, wood and plastic. Even metal will burn provided the temperature is high enough.
Sufficient quantities of oxygen are usually supplied by the air, and the energy to light a fire is produced by friction or sparks.

What are the two types of flame?
Blue Flame=Can't see (hotter then yellow flame) Yellow Flame (safety flame)=visible
Is a yellow flame of a Bunsen burner hotter than the blue flame?
No, a yellow flame is colder than a blue flame.
How do you get blue flame to yellow flame?
You reduce the supply of fuel. A "yellow" flame is a lot cooler than a "blue" flame. As it pertains to Chemistry, the dominant color for a nonluminous flame (yellow) is blue.
Does a yellow flame produces more energy or does a blue flame?
yellow
What causes the Bunsen burner flame to be noisy?
There are actually two flames that appear one is yellow & other is blue. And the blue flame makes more noise than the yellow.I think it is the sound of air rushing through the vents to get to the flame. The reason you get the yellow flame is that the gas is not burning completely. It is when you open up the vents that the flame is adjusted to blue.
What makes a yellow flame smokey?
Impurities in the matter being burnt.
What kind of flame is a yellow flame called?
A yellow flame is named as a safety flame as it isn't as hot as the blue flame
What are the two types of flame?

When is the flame test applicable?
It is usually used for when one is trying to figure out the chemical make up of an unknown substance. Depending on what color the substance makes during a flame test will help you figure out what it is composed of.

Does a yellow flame produces more energy or does a blue flame?
yellow
Why is a blue flame noisier than the yellow flame?
A blue flame is louder than a yellow flame because there is more oxygen (air) flow present than with a yellow flame. The yellow flame indicates a lack of oxygen and incomplete combustion of the methane gas.
How hot is the yellow flame on a fire?
The yellow flame? i do not know but the blue flame is 2732 degrees Fahrenheit
Why is it difficult to identify potassium ions and sodium ions in low sodium salt using a flame test?
When sodium is subjected to a flame test, it burns a bright yellow. This yellow flame can be brighter than the lilac flame color of the potassium, which makes it more difficult to distinguish between the sodium and potassium.
