What happened to the flame when you slowly opened the air holes?

As more air enters the Bunsen Burner, the flame turns from a flickering (wax candle effect) yellow to a fierce sounding blue, much hotter, flame.

In luminous flame the flame is produce when the air hole is open or close?
A bunsen burner (as used in a science lab or science classroom) will burn quietly, and a flickery yellow (like a wax candle) if the air hole is closed, or closed too much. If the air holes is opened, the flame will turn bluish and become noisy and hotter as more air mixes with the gas.
What happen to the flame when the air holes are closed of the bunsen burners?
It gains a yellow colour and becomes large and wavy hence luminous flame
Why is it safer to close the air holes to obtain a luminous flame?
When the air hole on a Bunsen burner is closed, air is excluded, so the flame becomes a yellowish candle-like flame.
How does air escape from a balloon while it is tied?
The material of the balloon has pores- tiny holes too small to see without a microscope- but big enough to let air molecules slowly escape.
Will an object with holes bob up and down in the water or will it sink if it floated before you put holes in it?
It depends on the boyancy of the material and the location of the holes. A ship holed below the waterline will sink. A body board with holes in will float.
When evaporating dish is held over the flame ( air holes are closed )?
I assume the air holes are on a bunsen burner? In which case, when the air hole is closed the flame glows yellow, is less hot, and is more like the flame on a wax candle. When the air hole is opened, air is drawn in and the flame burns blue and produces a fiercer heat.
What flame is what you called when air holes are closed?
Safety flame
What causes the luminousity of a flame?
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
What is turned to used to change the type of flame a Bunsen burner produces?
You would turn the collar on a Bunsen Burner so that the holes are exposing the flame to more oxygen to produce a blue flame. Close the holes by turning the collar to turn it back to the yellow (dirty) flame.
What the color of flame when opening air holes?
please answer this question
Bunsen burner blue flame?
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.

Why is the color of laboratory flame blue?
The throat holes on the burner are fully open. The color of the flame reflect the composition of the substance being burnt

My dad opened his shed one day to find it half full of sand he cleared it but at Christmas it happened again there are no large holes for the sand to come through?
You have termites in there-their droppings look like sand
What do you do when you gotten bitten by a lizard in the book holes?
You die slowly and painfully.
