When heated each element produces a series of thin colored lines called?
Spectrum or spectra
How can an element have freezing point at 200 degrees F?
an element's freezing point is the temperature at which the element becomes solid. some element's don't melt til heated to very high temperatures, and could therefore have a freezing point in the 100s of degrees.
Is an element's flame color a chemical characteristic?
The color of the light emitted by an element heated within a flame is a physical characteristic, but this particular physical characteristic is itself determined by a chemical characteristic: the distribution of electron energy levels within the element.
What element is is shiny black solid but gives off a purple vapor when heated?
Iodine on heating gives off dense purple vapor.
Which heating element is used in a heater?
Heating element is the main part of the ironbox which gets heated as current passes through it. We have to use the material for heating element with features such as: 1) high melting point 2) high specific resistance 3) not easily oxidised. (most important point) Hence the alloy NICHROME ( nickel and chromium) is used for heating element because it is not oxidised even at high temperatures.
What does every element emit if it is heated by passing an electric discharge through its gas or vapor?
A specific pattern of light. This permits elements to be identified by an instrument known as a spectroscope.
What is the glowing trail that results when a meteroid burns up in earths atmosphere?
Air heated to incandescence.
What is the filament purpose?
If you are asking about a light bulb, the threadlike conductor, often of tungsten, that is heated to incandescence by the passage of current
How was helium identified on the sun with a spectroscope?
Every element, when heated, sends out light with characteristic spectral lines. These same lines are also absorbed when the element is present in an atmosphere between a light source and the observer. When studying spectral lines of the sun some lines were noted that were not known on earth, from which we concluded that there must be an inknown new element. Which was subsequently found on earth.
Does an element melt when heated?
depends on the element
What is the term for a metiorite which enters earths atmosphere?
The streak of light across the sky caused when a space rock falls through the atmosphere and is heated to incandescence is a "meteor".
Conclusion in flame test?
During a flame test, elements are heated, and their, electrons of the atoms gain energy from the flame. When they lose this energy, they emit colors of visible light. Since each element has its own specific light, you can easily identify which element has been heated
What element gives a green flame when it is heated?
Earth.
What element is heated with rubber to make it vulcanized?
Sulfur
Property of the filament that makes it light up when electricity flows through it?
Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.
Meteors are rocks from outer space that?
Meteors are rocks from outer space that strike the Earth's atmosphere and are heated to incandescence (glowing heat) by friction. Most are completely vaporized, but some do fall to Earth.
What element sublimes when gently heated?
Iodine is the element that undergoes sublimation when exposed to air.
