Why air mix with the gas in the barrel of the burner before the gas is burned?
Heat+oxygen+Fuel=FireHEAT IS MIXED WITH GAS TO MAKE A HOTTER FLAME
Why is the blue flame on the Bunsen burner used for heating?
It's hotter than the yellow flame.
Which is dangerous the yellow flame or the blue flame?
A blue flame is hotter than a yellow flame. First, "...the blue flame..." IS NOT more dangerous than "...the yellow flame." The yellow flame is more dangerous because it is an indicator of IMCOMPLETE COMBUSTION resulting from burning with a shortage of air, and thus not enough oxygen. The reason this is dangerous, actually DEADLY, is that when combustion [burning] occurs in an oxygen deficient atmosphere, one of the major byproducts of that combustion process is CARBON MONOXIDE, a colorless, odorless, and tasteless gas which is toxic and therefore deadly to any creature that breathes air.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
Parts of a Bunsen burner adjusted?
There are two adjustable parts on the Bunsen burner, the knob to control gas flow and the rotation of the collar to control air flow. The gas flow control, adjusts the size of the flame by controlling how much gas is burned. While the collar controls the intensity of the flame by controlling how completely the gas burns, more complete combustion the hotter the flame. These are the two parts to adjust a Bunsen burner, I hope I have answered your question.
Why air mix with the gas in the barrel of the burner before the gas is burned?

What happens when the air is mixed with the gas coming from a Bunsen burner?
Opening the air hole collar to mix air with the fuel gas results in a hotter flame.
Is gas fires hotter than wood fires?
gas flame
How can you tell if there is too much air mixing with the gas in the Bunsen burner?
The more air the fiercer the flame and the hotter the flame.
How can you make a flame hotter on a Bunsen burner?
Turn the collar and the flame will get hotter
When is a Bunsen burner flame at its hottest and why?
When it is on a blue flame because the blue flame is hotter than the yellow flame due to the mixture of air and gas. Im Year 7 Guys you should know this!
Explain why opening the air hole of a Bunsen burner makes the flame hotter.?
Because more air is able to fuel the flame's reaction; the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter.
Is green fire hotter then blue fire?
Assuming we're not throwing ions into the flame and the color is due strictly to temperature, the blue flame is hotter.The problem is that flames can be different colors for reasons other than temperature. Specifically, they may contain ionized materials with strong emission lines that color the flame. Probably the easiest example to observe using ordinary household materials is sodium which gives an orangish yellow color (easily seen by dropping a few crystals of table salt into the flame of a gas stove).The reason that hotter flames are blue is that blue light is more energetic than red light. A hotter flame has more energy, and therefore generates more energetic light.
Why does a Bunsen burner have an air hole?
It's to allow air to mix with the gas before burning - creating a hotter flame.
How can you tell if there is too much air mixing with the gas in a Bunsen burner?
The more air the fiercer the flame and the hotter the flame.
Why is it when the Bunsen burner hole is completely close they fire get bigger and hotter?
By "hole" do you mean the air inlet? (If you close the gas inlet, the fire goes away). If so, it gets bigger because it takes longer for sufficient oxygen to mix with the gas to allow it to combust. However, the flame actually gets cooler, not hotter; the blue cone-shaped flame you get when the air/gas ratio is properly adjusted is significantly hotter than the large yellow/red flame you get when there's insufficient air in the mix.
What part of a flame burns hotter?
The blue portion of a flame is the hottest
