If you heat a metal it will begin to glow faintly red at around 500ºC, or about 950ºF. If you continue to heat it, by 800ºC (about 1450ºF) the glow will a dull cherry red and at about 1100ºC (about 2000ºF) the colour will be a lemon or light yellow colour. Finally, at temperatures above about 1300ºC (about 2400ºF) the glow appears white, and very bright. Precautions must be taken, as looking directly at an object at this temperature can damage your vision.
What else can I help you with?
Is charcoal a metal or nonmetal?
Charcoal is not a metal or a nonmetal. It is a form of carbon that is produced by heating organic materials in the absence of oxygen.
What is the meaning of incandescence?
the state of glowing while at a high temperature, caused by electrons in vibration atoms and molecules that are shaken in and out of their stable energy levels, emitting radiant energy in the process. The peak frequency of radiant energy is proportional to the absolute temperature of a heated substance
What metal is produced by heating ore?
Heating ore usually produces metal in its pure form through a process called smelting. The type of metal produced depends on the ore being heated - common metals produced include iron from iron ore, copper from copper ore, and aluminum from bauxite ore.
What is a metal that releases a blue - white light when burned?
The metal that releases a blue-white light when burned is magnesium. When ignited, magnesium burns with a bright white flame due to the intense heat produced during the combustion process.
Why can some metals be extracted from compounds by heating carbon?
Heating carbon with metal compounds can help extract the metal because carbon can act as a reducing agent. During the heating process, carbon reacts with the metal compound, and the carbon removes oxygen from the metal compound, leaving behind the pure metal. This process is known as a reduction reaction.
What is a metal that glows when electricity is passed through it?
Phosphorus is a non-metal that glows when electricity is passed through it. It emits a light known as phosphorescence.
Why scientists use tungsten metal in manufacturing the filament of the light bulbs?
it glows and emits light.
When a piece of metal heats up and glows it gives off light waves and what?
When a piece of metal heats up and glows, it emits light waves due to the increased kinetic energy of its atoms. This phenomenon is known as incandescence. The color of the light emitted depends on the temperature of the metal.
What is something created when filament that becomes so hot it glows?
A light bulb is created when a filament becomes so hot that it glows. The high temperature causes the metal filament to emit light, which produces illumination in the bulb.
Is charcoal a metal or nonmetal?
Charcoal is not a metal or a nonmetal. It is a form of carbon that is produced by heating organic materials in the absence of oxygen.

Why tungsten glows?
tungsten is a poor conductor of electricity,tungsten glows when electrical energy from the energy source is flowing through the conductor of electricity and when electrical energy reach the metal filament(tungsten) the tungsten gets electrical energy and produce heat when it became white-hot and the tungsten glows the glows is called light.
What metal is produced by heating ore?
Heating ore usually produces metal in its pure form through a process called smelting. The type of metal produced depends on the ore being heated - common metals produced include iron from iron ore, copper from copper ore, and aluminum from bauxite ore.
Which metal ion produces the light with the highest energy?
K+ produces the highest energy light. Na+ is a lie
What is fragment of rock ice or metal that glows as it collides atmosphere?
meteor.
How do light-bulbs work?
An electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation.
If a metal bar glowed red hot in a fire would it be a chemical change?
Yes, the metal bar undergoing a color change due to heating in a fire is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties. Heating a metal bar until it glows red hot does not alter its chemical composition.
