The hottest flame is blue. Here’s a breakdown of flame colors and their temperatures:
- Blue: The hottest flame, reaching temperatures of around 2,500 to 3,000 degrees Fahrenheit (1,400 to 1,600 degrees Celsius). This indicates complete combustion with plenty of oxygen.
- White: Very hot, around 1,300 to 1,500 degrees Fahrenheit (700 to 800 degrees Celsius).
- Yellow: Moderately hot, around 1,100 to 1,200 degrees Fahrenheit (600 to 650 degrees Celsius).
- Orange: Less hot than yellow, around 2,000 degrees Fahrenheit (1,100 degrees Celsius).
- Red: The coolest visible flame, around 525 to 1,000 degrees Fahrenheit (275 to 550 degrees Celsius).
Why blue is the hottest?
The color of a flame is determined by the wavelengths of light it emits. Hotter flames emit shorter wavelengths, which appear as blue. This is because the molecules in the flame are vibrating more rapidly at higher temperatures, producing more energetic light.
