is it something to do with oxygen?

yes, the blue flame doesn't contain oxygen, the orange flame is burning oxygen

If the flame is not coloured by contact with metal then a blue flame indicates that the gas has been completely burned. If the gas does not completely burn (due to a restricted air supply) then some of the gas produces carbon and this causes the flame to get it's orange colour. Even less complete burning will produce a yellow flame.
Frequently the colour of a flame is due to it coming into contact with metals or their compounds. Calcium from water deposits gives a flame an orange colour. Sodium from salt or washing powder gives a bright yellow flame.

Yes, it has something to do with oxygen. The blue flame has no oxygen residing in it, and the orange flame does have oxygen. Also, it can vary between what you are burning. Things like magnesium give off orange flames and yellow flames a lot.
Hope this has helped you!

With a laboratory burner you must adjust the air vents to allow the optimum amount of air (oxygen) to reach the gas and combust.
An orange/yellow flame means that there is not enough oxygen to burn all the gas molecules. This is incomplete combustion. This flame is call "luminous" because it gives off more light than heat.
A blue flame means that there is sufficient oxygen to burn the gas completely. This flame is called "nonluminous" because more of the energy is released in the short wave-length colors and more heat is given off.

I hope you mean orange! in which case this is because an orange flame does not have enough oxygen in it to burn all the fuel completely and then the carbon particles colour the flame. A blue flame is burning completely so there is no excess carbon to colour the flame. Hope this helps.

yes, the blue flame has a lot more oxygen in it and is a lot hotter then the yellow, the blue flame is known as the heating flame,
the yellow flame has less oxygen and is cooler and this is called the saftey flame. the reason that it is yellow is because it is incomplete combustion so it doesnt burn all the energy so leaves soot

This the classic flame test.
When a copper salt eg copper sulphate is dissolved in water it produced a blue solution. A ni-chrome wire is dipped in to this solution and then passed through a Bunsen flame. The blue/green colour of the flame is the flame test indicates copper ions present.
Similarly, when a sodium salt eg sodium chloride (table salt) is tested a yellow/orange colour of the flame indicates sodium ions present.

To a certain degree, yes. More oxygen allows the combustion to proceed at a higher temperature, and the higher the temperature, the lest reddish and the more whitish the color of the flame.

even with the undeniable actuality for you to be able to imagine of pink is warmth, blue is hotter. evaluate it like gas from a gas variety or warmth water tank. It receives warmth quite quick and that is through actuality it really is a blue flame. There are diverse technical causes that the hearth is blue. really, Hell is likely blue and under no circumstances pink. HAHAHA. only a theory from a bible student.

blue falme uses more oxygen than a orange one. to get a blue flame on a bunsen burner you have to open a little switch
