What else can I help you with?
Why is the sodium flame is not visible through the cobalt glass?
The cobalt glass absorbs specific wavelengths of light, including those emitted by the sodium flame. This absorption of light by the cobalt glass results in the sodium flame not being visible when viewed through it.
What is the colour of sodium and potassium flame through a cobalt glass?
The flame color of sodium through a cobalt glass appears yellow, while the flame color of potassium through a cobalt glass appears lilac or pale violet. The cobalt glass filters out certain colors, allowing specific wavelengths to pass through, which affects the observed flame color.
Why does the candle flame goes out when placing a glass over it?
When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.
If you want to melt a glass rod faster which of the region of the burner will you use?
You should use the inner blue cone region of the burner flame to melt the glass rod faster. This region of the flame is the hottest and most intense, providing the necessary heat to quickly melt the glass.
What happens when you cover the top of a glass that has a burning candle inside?
When you cover the top of a glass with a burning candle inside, you restrict the flow of oxygen to the flame. This causes the flame to consume the available oxygen within the glass, leading to the extinguishing of the flame due to lack of oxygen. Additionally, the heat and gases produced by the burning candle may build up within the glass.
What is the flame spread rating for glass?
Glass does not burn or contribute to flame spread, so it typically does not have a flame spread rating.
Does the flame from glass fire pits burn in colors of the glass?
well not usually when you keep trying your best to make the flame from glass fire pits burn in colors of the glass
Why is the sodium flame is not visible through the cobalt glass?

The flame color of sodium through a cobalt glass appears yellow, while the flame color of potassium through a cobalt glass appears lilac or pale violet. The cobalt glass filters out certain colors, allowing specific wavelengths to pass through, which affects the observed flame color.
How can a sun light a flame?

Why does a flame go out when it touches glass?
When a flame comes into contact with glass, the glass rapidly absorbs heat from the flame, leading to a sharp temperature drop at the point of contact. This sudden cooling can extinguish the flame by interrupting the combustion process, as the fire requires a certain temperature to sustain itself.
Are rocks organic or inorganic?
Rocks are classified as inorganic because they are composed of minerals and do not contain carbon-based molecules associated with living organisms. Organic materials, on the other hand, are derived from living organisms and typically consist of carbon and other elements.
How long does it take for glass to rot away?
Glass is inorganic, so it doesn't rot.Glass melts very slowly. Or Sublimates.
Why a candle gets extinguish when a glass is put over it?
When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.
Why does the candle flame goes out when placing a glass over it?
When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.
What color flame test does Potassium give with a cobalt glass?
Potassium gives a lilac or pale-violet flame test when viewed through a cobalt glass. The cobalt glass helps to filter out other colors from the flame, allowing the characteristic lilac color of potassium to become more visible.
What happens when you cover the top of a glass that has a burning candle inside?
When you cover the top of a glass with a burning candle inside, you restrict the flow of oxygen to the flame. This causes the flame to consume the available oxygen within the glass, leading to the extinguishing of the flame due to lack of oxygen. Additionally, the heat and gases produced by the burning candle may build up within the glass.
