Blue Flame=Can't see (hotter then yellow flame) Yellow Flame (safety flame)=visible
When the air hole is covered on the Bunsen Burner its oxygen supply is made smaller. This makes the flame turn YELLOW - This is considered to be the safety flame as it is the most visible to the eye and it radiates less heat. When the Bunsen burners air hole is fully open there is a super heated blue flame which is the product of complete combustion. Hope this helped :)
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.
No, a yellow flame is colder than a blue flame.
The color <> Blue flame is one of the hottest Yellow is one of the coolest
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.
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.

Etanol is burning with a faint blue-ish flame color
The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.
No, the blue part is the hottest. In fact, you should adjust the burner so that you only have a blue flame. A yellow/orange/red flame is indicative of incomplete combustion (generating carbon monoxide).

No, if the flame is totally blue and/or has no yellow, then that indicates complete combustion which results carbon dioxide [CO2] and water vapor, but no carbon monoxide [CO].

yes there is a flame at the top of a Bunsen burner. there are three different types light blue blue and yellow
yes, they are. here are the flame colors in order from hottest to coolest. white - hottest blue - hotter yellow - hot orange - cooler than yellow red - cooler than all of above
