Is heating tungsten until it glows red a chemical or physical change?
Heating tungsten until it glows red is a physical change because the composition of the tungsten does not change. The change in color is a result of the increased temperature causing the atoms to vibrate and emit visible light.
When using a Bunsen burner how can you tell if the reactant is burning or just heating the reaction?
When using a Bunsen burner, you can tell if the reactant is burning by observing the presence of a visible flame and the release of gases, such as smoke or soot, indicating combustion. If the reactant is simply heating, there will be no visible flame, and the reaction may produce heat without combustion signs, such as color changes or changes in state. Additionally, if the temperature of the reactant is increasing without producing flames or smoke, it is likely just heating.
Why does the heating coil become red hot and white hot?
The heating coil becomes red hot and then white hot due to the temperature increase as electrical current passes through it. When the coil heats up, it first emits visible red light as it reaches higher temperatures, indicating it's glowing due to incandescence. As the temperature rises further, it emits light in the blue and violet spectrum, making it appear white hot. The color change reflects the coil's increasing thermal energy and the wavelengths of light it emits.
Which color of visible light has the lowest frequency?
The color red has the lowest frequency of the visible light - violet has the highest
Does the flame of the gas stove give light of visible wavelength?
Certainly; you can see the light that it gives off.
Does CO2 have a color?
No, carbon dioxide (CO2) is a colorless gas at standard temperature and pressure. It is transparent to visible light, which means it does not have any visible color.
Is heating tungsten until it glows red a chemical or physical change?
Heating tungsten until it glows red is a physical change because the composition of the tungsten does not change. The change in color is a result of the increased temperature causing the atoms to vibrate and emit visible light.
What are 3 observable properties?
Any three of: Composition, size (dimensions), mass, temperature, visible-spectrum color.
What is the color of visible light determined by?
The color of visible light is determined by its wavelength.
What color is a star with 6000 degree celsius temperature?
A star with a temperature of 6000 degrees Celsius would appear white in color. This temperature corresponds to a star of spectral type A, which emits light across a range of visible wavelengths creating a white appearance.
What's the color of visible light?
Visible light includes any color that the eye can see.
What are visible characteristics?
Visible characteristics are characteristics that are visible. Haha no but they are your outside features.
How was infrared discovered?
According to NASA infrared radiation was first discovered in 1800, by a British astronomer named William Herschel. In an experiment to measure the difference in temperature between the colors in the visible spectrum, he placed thermometers in the path of light within each color of the visible spectrum. He observed an increase in temperature from blue to red, including an even warmer temperature measurement just beyond the red end of the visible spectrum.
What is the color of nitrogen monoxide?
Nitrogen monoxide is colorless gas; it is also known as Nitric oxide.
What caused some gas to be visible?
Gas is only visible by having a certain color: Chlorine: greenish yellow, Iodine: purple, Bromine: redish brown. No color, not visible.
Color of visible light?
VIBGYOR
What are all the combenations with color?
All the combinations of visible colour are included in the visible spectrum.
