Want this question answered?
Because if the air hole was wide open, the flame will be blue, which is going to be really hot so you have to leave it at a safety yellow flame which is when the air hole is closed when lit. It could be dangerous to leave a Bunsen burner on a blue flame. this is confusing, explain more clearly, geez is dat too much to ask?
A Safety Flame Is The Yellowy Orange Flame. It Is Called A Safety Flame Because You Can See It Unlike The Blue Flame
It depends what you want to do! A blue flame is typically much hotter than a yellow flame. Sometimes you want to heat something very hot, and sometimes you want to heat something gently... and so you can choose which part of the flame best suits the purpose! blue flame
By this I'm thinking your talking about a Bunsen burner? A flame should never be left unattended. You should have someone supervise it while you go or if this isn't a possibility then turn it off and then once you return put it back on. If none of this are possible turn the flame down onto a low heat ( i think it is a yellow flame) and make sure nothing around it can catch on fire/ no one else could knock it over.
because yellow flames dont burn effectively and leave carbon so burning with yellow flames leaves soot on the glassware
The flame of a Bunsen burner that is yellow in color will leave a black carbon residue due to the incorrect mixture of oxygen into the flame. Because there is not enough oxygen for complete combustion, the carbon reside is left behind. When the Bunsen flame has a sufficient amount of oxygen mixed in, hence the 'roaring flame', it has a blue color and does not leave a carbon residue due to complete combustion of the acetylene gas.
The yellow flame is more visible - making it easier for others to see. It's also a colder flame than the blue conical one.
because it isnt hot enough and will leave soot on the bottom of the thing you are heating
When you have to leave your Bunsen burner but need to keep it alight.

so when you leave the room the bunsen is in the nosier flame (roaring flame)tells the other people that the bunsen is on and they wouldn't burn themselfs
It is less hot
