Which is hotter red or blue fire?

Which is hotter red or blue fire?

Because, flames consists of photons which can be defined as quantum of energies of varying freq. and wavelengths in the electromagnetic spectrum, blue has higher freq. than the red colour. Thus, energy is directly proportional to energy which makes the blue flame hotter than the red flame.

What is hotter blue flame or orange?

Blue Flames Indicate Temperatures of 2,300 to 3,000 Degrees Blue flames burn hotter than orange flames, with temperatures reaching up to 3,000 degrees Fahrenheit. They heat up more quickly and to higher temperatures than fires using other fuel sources, resulting in a blue flame.

Why do flames turn blue?

When enough air is supplied, no soot is produced and the flame becomes blue. A blue-colored flame only emerges when the amount of soot decreases and the blue emissions from excited molecular radicals become dominant, though the blue can often be seen near the base of candles where airborne soot is less concentrated.

Which star is hotter Mira or the sun?

Mira is cooler and redder but intrinsically brighter than the Sun. Mira is hotter and bluer but intrinsically fainter than the Sun.

What are the stages of a dying star?

When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.

What color star is the coldest?

red

Why sometimes there is no stars at night?

The combination of all the streetlights, spotlights, and building lights work together to fade our night sky. The more light pollution there is, the less black the night appears – the sky will only darken to a gray – and the more light pollution, the fewer stars are visible.

What is the name of the coolest star?

One way that stars are categorized is by temperature. Since the temperature of a star can determine its visual color, this category scheme is known as spectral type. The main categories of spectral type are M, K, G, F, A, B, and O. The coolest stars (red dwarfs) being M, and the hottest stars being O.
