What holds a small solid in a Bunsen burner flame?
A metal wire or ceramic triangle called a "crucible" is typically used to hold a small solid in a Bunsen burner flame during heating. This allows for better heat transfer and prevents the solid from rolling out of the flame.
What apparatus is used for heating a solid directly over a flame?
The simplest tool for the job is the "Bunsen" burner, named for its inventor.
How do you heat a solid in a Bunsen flame?
A solid can be heated in a Bunsen flame by placing it on a heat-resistant material like a ceramic or wire gauze, and then holding it above the flame. The solid should be slowly moved through the outer part of the flame, where the temperature is higher, to ensure even heating. It's important to monitor the solid closely to prevent overheating or combustion.
What is a lab burner?
A lab burner is a device used in laboratories to provide heat for various purposes, such as heating solutions or sterilizing equipment. It typically consists of a gas source that is ignited to produce a flame that can be adjusted in size and temperature.
Is copper in a Bunsen burner a physical or chemical change?
Using a Bunsen burner to heat copper is a physical change. The copper undergoes a change in its physical state from solid to liquid without changing its chemical composition.

What item can heat a solid in the presence of air?
A Bunsen burner can heat a solid in the presence of air by producing a hot flame that can be directed onto the solid material for heating purposes.
What compound does not decompose when it is heated with a Bunsen burner?
Silicon dioxide (SiO2), commonly known as quartz, does not decompose when heated with a Bunsen burner. This is because SiO2 has a very high melting point, around 1,710°C, which is above the typical temperature of a Bunsen burner flame. Instead of decomposing, it stays solid and retains its structure.
What is the difference between Bunsen burner and alcohol lamp?
Bunsen Burner: - Uses Gas - Achieves up to roaring blue flame - Used to melt solid objects Alcohol Lamp: - Uses Alcohol - Achieves Yellow flame only - Used to boil water
What is the best way to prove or disprove that NaCl solid is in fact a piece of NaCl solid?
Put it under the flame of a bunsen burner, and if it turns bright orange, then it is NaCl. Also, if you put some Silver Nitrate (AgNO4) into it, and a cloudy white precipitate comes out, you also know it is NaCl. and it will be safe to taste!
At what point does ice melt over a bunson burner?
Ice begins to melt when its temperature reaches 0 degrees Celsius (32 degrees Fahrenheit), transitioning from a solid to a liquid state. When exposed to a Bunsen burner, the heat from the flame will increase the temperature of the ice, causing it to melt more rapidly.

Why is solid naphthalene not heated directly with a Bunsen burner?
Solid naphthalene is not heated directly with a Bunsen burner because it can undergo sublimation, meaning it can turn directly from a solid to a gas without passing through the liquid phase. This process can lead to the rapid vaporization and combustion of naphthalene, increasing the risk of fire or explosion.
Is heating sodium chloride with a Bunsen burner a chemical change?
No. It is a physical change. It only melts.
