The blue flame is called a roaring flame and the yellow flame is called the safety flame.
Oxidation
to heat tings up with and also if you hold a china lid over a yellow safty flame and then over a blue flame the soot which is developed is burnt away
Most things in chemistry.. Usually you would use a blue Bunsen flame (half open at the bottom) for heating almost everything. The yellow flame is only a safety flame, as you can't see a blue one all that well, and it's not used for heating because it produces soot
actually, the hottest part of a fire IS the blue-green part!
The blue flame is called a roaring flame and the yellow flame is called the safety flame.
the colour of the roaring flame is blue
A non luminous, roaring, blue flame. 🔥 🔥 🔥
The Blue Flame Will Be Noisier. The Yellow Flame Is Called A Safety Flame Because Everyone can See it. There Are Two Blue Flames: Medium Roaring The Roaring Flame Has A Blue Cone In The Middle Of The Flame And It Is The Hottest. It Also Has More Oxygen. But Overall, The Blue Flames Will Be Noisier Than The Yellow Flame.
When set to a roaring flame, there are what looks like cones of different shades of blue and orange. The hottest part of the flame, when set to roaring, is at the tip of the blue cone.
Oxidation
The maximal temperature is in the roaring blue flame - up to 700 0C.
The hottest part is the internal flame triangle in the blue flame (roaring blue flame) - up to 700 0C.
Guessing 'Y fflam las ruol'.
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.
The different flames are a) the luminous flame b) the blue flame c) the roaring flame The luminous flame is for safety and when the burner is not in use, should be left on it because you can see the flame becuase it is yellow. The hole must be closed for the luminous flame. The blue flame is generally used for expirements and is slightly weaker than the roaring flame. It can be gotten through opening the nole half-way. The roaring flame is only used in expirements when you need extra-strength becuase it is the hottest and most powerful flame. It is achevied through a fully opened hole.
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
