The higher up the flame, the colder it is. Just above the blue cone is the hottest. Close the air inlet and heat above a yellow flame for gentle heat.

How do you control the type of Bunsen flame?
Decide which flame to use. If the air hole on the Bunsen is open you will get a roaring flame a more gentle heat, close the air hole a Little flame will be quiet.
Why are pans placed over a flame and not on the side of the flame?
Pans are placed over a flame and not on the side of the flame, because it is an energy transfer by direct contact called conduction. And as you can see, pans are usually made of metals, wherein metals are a good conductor of heat unlike wood, which is a poor conductor of heat.

How do i re-melt candles?
Warm them up. Ideally you should use a double boiler, or some other gentle heat source instead of an open flame.
What is a Bunsen burner?
A Bunsen Burner is a controlled gas-burning heat source (a "gas candle") that supplies direct heat or flame for scientific experiments and research. (The flame can be blocked by screens to reduce the deposition of soot on test tubes and beakers.)
What is the difference between flame and heat?
"Flame" is the visible energy when burning something. "Heat" is given off a flame and countless other things. Flame produces heat, but heat does not always generate from flame, and heat almost never produces flame (friction might count). And if you want the definitions: HEAT: a form of energy that is transferred by a difference in temperature. FLAME: the process of combustion of materials producing heat and light and (often) smoke. If you want to think of it a different way: Flame is what you see when you look at a fire and heat if what you feel from the fire.
How you can calculate the heat irradiative by the flame?
You can calculate the heat of a flame by its color. Normally the hotter that the flame is the bluer that the flame will burn. If the flame is red that means it is burning at a cooler temerature.
Radiation is the type of heat roasts the marshmallows?
When roasting a marshmallow the transfer of heat from the flame to the marshmallow is radiation.Radiation is the transfer of heat through energy waves. It can actually be considered conduction as well if you place the marshmallow into the flame, since that is the direct transfer of heat.
What kind of heat transfer is a marshmallow over a bonfire?
A marshmallow over a bonfire is a radiant heat transfer. The marshmallows are not in direct contact with the flame but are held very close to reduce burning.
What two types of heat treatments are there?
Superficial heat treatments apply heat to the outside of the body. Deep heat treatments direct heat toward specific inner tissues through ultrasound or by electric current.
Which flame has more heat a steady blue flame or a yellow flame?
Blue flame. because it does not have carbon
What is the possessive of flame?
The possessive form for the noun flame is flame's.Example: I feel the flame's heat.
