The glow of gas occurs when it is energized, such as by heat or electric currents, causing the atoms or molecules to become excited. As they return to their lower energy states, they release energy in the form of light, a process known as photon emission. The specific color of the glow depends on the type of gas and the energy levels of its atoms, as different elements emit different wavelengths of light when energized. This phenomenon is commonly observed in neon lights and other gas discharge tubes.

How do you light the pilot on a whirlpool gas dryer?

I don't know of any dryers that have a pilot light. They have glow plugs which glow red hot before the gas valve is opened so that the gas will ignite. If the glow plug is not working it probably has a crack and needs to be replaced. The dryer will not start without it.


Why is argon used in glow sticks?

Argon is used in glow sticks because it is an inert gas that is chemically stable and non-reactive. It helps prevent the chemicals in the glow stick from reacting too quickly, allowing for a longer-lasting and more controlled glow.


Is there neon in glow sticks?

Yes, there is no neon gas in glow sticks. Glow sticks typically contain a combination of hydrogen peroxide, a phenyl oxalate ester, and a fluorescent dye. When the glow stick is activated by bending it to break the inner glass vial, the chemical reaction between the ingredients produces light without the need for neon gas.


Is there a neon white?

Yes, but the gas is carbon dioxide, not neon. Actual neon lights glow red. Different gases glow different colors.


What are the physical characteristics of hydrogen?

It is a colorless gas with purple glow in its plasma state.


Does neon glow in the dark?

Neon does not glow in the dark but it does glow in black light or UV light. Because neon colors are so bright when illuminated with light, it gives the appearance that neon colors would glow in the dark.No, it is a colourless gas but it will glow red if you pass an electrical current through it.Neon is also another way of describing brightly coloured things, but they don't glow in the dark either.


Why does the hydrogen gas produced in laboratory not glow and emit radiations?

Hydrogen gas produced in a laboratory does not glow or emit radiation because it exists in its ground state. This means that the electrons in the hydrogen atoms are in their lowest energy levels and do not emit light when excited. To observe the glow and radiation emission from hydrogen gas, it needs to be excited to higher energy levels, such as in a plasma state.


Why do burnt ends of matches glow when blown on?

Burnt ends of matches glow once blown out and blown on because fire feeds off oxygen and the half-alive embers on the tip of the match glow in response to the gas


Is the element radon used in glow sticks?

No, radon is not used in glow sticks. Glow sticks typically contain chemicals that produce light through a chemical reaction, such as hydrogen peroxide and phenyl oxalate ester. Radon is a radioactive gas and not suitable for use in glow sticks.
