Where is the hottest part of the flame on a Bunsen burner?

Determining the hottest part of the Bunsen burner using a paper clip and match. Notice that the paperclip glows red hot at the top of the inner cone of the flame, At the bottom of the Bunsen burner it is much cooler.
A.

What color is the hottest part of the flame?

Color also tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red.
  • Why is the hottest part of the flame blue?

    This is due to incandescence of very fine soot particles that are produced in the flame. With increasing oxygen supply, less black body-radiating soot is produced due to a more complete combustion and the reaction creates enough energy to excite and ionize gas molecules in the flame, leading to a blue appearance.
  • How hot is the coldest fire?

    Cool flame. Cool flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture.
  • What is the hottest part of a flame on a torch?

    The outer flame is a dark transparent blue. The inner flame is lighter, opaque in color, and comes to a sharp tip inside the outer flame. Just in front of that lighter flame is the “sweet spot,” or the hottest part of the flame. Use this point to quickly heat metal and flow solder.
B.

Is a white flame hotter than blue?

Note that a blue propane flame is hotter than a yellow one, but this is just due to efficient combustion, and the difference is likely in the hundreds of degrees Kelvin, not thousands. White fire might be something extremely hot, but it's more likely a mixture of several emission spectra.
  • What is the color of the coolest stars?

    Our Sun is a type G star, which are yellow stars with surface temperatures of about 6000 °C, or 11,000 °F. Type A stars, which are hotter, are white in color and maintain temperatures of around 10,000 °C or 18,000 °F. The hottest of the types, B and O, are blue stars while the coolest of type M are red in color and
  • Is a red or blue star hotter?

    So, that should answer your question: the hotter something is, the greater the frequency of radiation it emits. But since blue light is higher frequency than red light, that means that things that glow red are cooler than things that glow blue. So: red stars are cooler!
  • Is fire burnt?

C.

Where is the hottest part of a candle flame and why?

The hottest parts of a candle flame are actually the blue, almost invisible area near the base, where oxygen is drawn in, and the blue/white part around the edge, where the flame meets the oxygen-rich air all around it. The flame gets progressively cooler as you move in from the outside edge toward the wick.
  • Why is the hottest part of the flame blue?

  • Is a candle burning a chemical or physical change?

    In a burning candle, there are both physical and chemical changes. The melting of the solid wax to form liquid wax and the evaporation of liquid wax to form wax vapour are physical changes. The wax vapour reacts with oxygen in the air to form new substances including carbon dioxide and ash.
