Nichrome wire produces an orange light when heated in a flame due to its high resistance and the temperature it reaches when current flows through it. As the wire heats up, it emits thermal radiation, which includes visible light. The orange color specifically arises from the thermal emission spectrum of the wire, where it radiates light in the orange-red region as it approaches higher temperatures, similar to how heated metals glow. This phenomenon is a result of blackbody radiation, where the color of the emitted light corresponds to the temperature of the material.

Why are flames orange?
Flames aren't always orange, their colour is depenant on what material is being burned. A substance with contains a high percentage of copper will burn with a green flame and if is contains strontium the flame would be red. Different substances produce different flame colours and this property can be used to identify substances. Orange flames indicate the presence of Sodium.
What is the flame color after burning gold?
Gold does not produce a flame color when burned. When heated, gold will melt and form a shiny, metallic liquid.
What color does helium burn in a flame test?
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Which elements give off a color when heated and what color?
Different elements produce different colors when heated. Here are a few examples: Lithium produces a red flame Sodium produces a yellow flame Copper produces a blue-green flame Potassium produces a lilac flame Barium produces a pale green flame
Does beryllium give a red flame test?
Its like Mg, it has no colour. So bright light
What ions gives a bright orange flame test?
The presence of sodium ions typically gives a bright orange flame test. Sodium compounds such as sodium chloride or sodium carbonate produce this distinctive color when heated in a flame.
Why is the gas flame orange?
The gas flame appears orange due to the presence of sodium particles in the gas, which emit a characteristic orange light when heated.
What colour of flame does sodium chloride produce when heated?
Sodium chloride does not produce a flame when heated. It simply melts into a liquid state and eventually vaporizes.
Which combination describes the flame color of the compound when heated?
Which combination describes the flame color of the compound when heated?
What happens to lead nitrate in a flame test?
It depends on the conentration, did a test today with several nitrates (incl. lead nitrate) and they were all yellow/orange...
Why charcoal does not produce flame?
Charcoal does produce a flame when it is heated to a high enough temperature, usually found when blowing red hot coals till the flames start

What color is silver in the flame test?
Silver does not produce a distinctive color in a flame test. It does not exhibit a characteristic flame color like other elements when heated in a flame.
Why is there green flame when you burn magazines?
The green flame is likely due to the presence of copper in the ink used in the magazines. When copper is heated, it can produce a green flame.
What is the flame color of iron nitrate?
Iron nitrate typically produces a yellow-orange flame color when it is heated. This color is due to the presence of iron ions in the compound.
What is the flame color after burning gold?
Gold does not produce a flame color when burned. When heated, gold will melt and form a shiny, metallic liquid.
What is the flame test for aluminum?
When aluminum is subjected to a flame test, it does not produce a distinct color flame. This is because aluminum does not have any characteristic flame color associated with it, unlike other elements that produce specific colors when heated.
