Why does the blue flame on a Bunsen burner make metal things red when they are held in the flame for a long time?
The blue flame of a Bunsen burner is hotter than the yellow flame. When a metal object is held in the blue flame for a long time, it absorbs heat and emits light, resulting in the metal glowing red due to incandescence. This happens as the metal reaches a temperature at which it begins to emit visible light.
The process of combustion occurring without an open flame is called?
The process of combustion occurring without an open flame is called spontaneous combustion. This phenomenon usually happens when a material self-heats to its ignition temperature without an external heat source.
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.
When water is in a pan over a flame why does the water get hot?
When water is in a pan over a flame, the heat from the flame is transferred to the water through conduction. As the water molecules gain energy, they move faster, which causes the overall temperature of the water to increase. This process continues until the water reaches its boiling point and starts to evaporate.
What happens to a metal atom when a splint soaked with chloride and placed in a flame and color is produced?
When a metal atom is heated in a flame with a chloride compound, the metal atom absorbs energy and is excited to a higher energy state. As the metal atom returns to its ground state, it emits light of a specific wavelength, resulting in the production of a characteristic color. This color can be used to identify the metal present in the compound.
What happens to pressure in a metal spray when heated up?
It heats up
What happens when each nitrate salt is put into the flame?
The color of the flame depends on the metal from the salt.

What heats a burner flame?
gas
Why flame on a candle burns erect?
The flame heats the air and it is lighter so it goes upwards.
How many squire feets does the MHVFB10LP propane blue flame heats?
Heats up to 300 sq ft

Why do you use a metal-nitrate in a flame test?
Metal nitrates are used in flame tests because they are easily converted into metal ions when heated in a flame. The metal ions then emit characteristic colors of light, allowing for the identification of the metal present based on the color produced.

Metal that bursts into flame when it reacts with water?
Potassium is the only metal (alkali metal) where a flame is present. Lithium and sodium fizz but there is no flame. Caesium, francium and rubidium all explode on contact with water.
