Does glass heated in a hot flame glow and becomes fluid?
Glass can soften and become pliable when heated in a hot flame, but it does not glow like metal does when it reaches high temperatures. It does not become fully fluid like a liquid, but it can become molten and flow like a thick syrup.
Why is black soot formed when the flame is luminous?
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
Why sugar not heated directly with a Bunsen flame?
Sugar should not be heated directly with a Bunsen flame because it can quickly melt and possibly catch fire. The high heat can cause rapid caramelization and the release of flammable gases, leading to a potential fire hazard. It is safer to use indirect heat sources, such as a double boiler or a hot plate, to heat sugar gradually and prevent overheating.
Which elements give off a color when heated and what color?
Different elements produce different colors when heated. Here are a few examples: Lithium produces a red flame Sodium produces a yellow flame Copper produces a blue-green flame Potassium produces a lilac flame Barium produces a pale green flame
What conditions would a flame become luminous?
A flame becomes luminous when it reaches a high enough temperature to emit visible light. This usually occurs when the flame is fuel-rich and produces soot particles that glow as they burn. They can also become luminous in the presence of certain chemical compounds, such as salts, that emit colorful light when heated.
What element gives a green flame when it is heated?
Boron is the element that gives a green flame when it is heated.
Which is better-poison serpent or flame sagittario or rock Aries?
poison serpent
Is the flame test for the metal or for the chlorine?
The flame test is for the metal. When a metal is heated in a flame, electrons in the metal atoms become excited and jump to higher energy levels, emitting characteristic colors of light. This helps identify the metal present.
Which combination describes the flame color of the compound when heated?
Which combination describes the flame color of the compound when heated?

What is the Colour of sulfur heated into oxygen?
Sulfur heated in oxygen produces a blue flame.
What colour of flame does sodium chloride produce when heated?
Sodium chloride does not produce a flame when heated. It simply melts into a liquid state and eventually vaporizes.
Why is black soot formed when the flame is luminous?
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
What is the flame color of Cucl2?
The flame color of CuCl2 is blue-green. This color is often observed when copper compounds are heated in a flame.

What two things are not heated with naked flame?
Lead And Cryptonite
What yellow flame indicate in flame test?
A yellow flame in a flame test usually indicates the presence of sodium in the sample being tested. Sodium typically produces a bright yellow flame when heated.
