How do you regulate the size of a flame when using a Bunsen Burner?
by limiting the amount of oxygen you can get incomplete combustion where the flame is coolest and complete where it goes blue and is bare hot
Where does the air enter the Bunsen burner?
There is an opening at the bottom of the barrel above where the gas enters. There will be a valve or collar that changes the size of the opening.
If you put a pot on the stove the pot becomes hot. The heat is transferred to the pot on the burner by radiation. Please select the best answer from the choices provided T F?
It depends on the size of the flame. If the flame is large enough so that it touches the bottom of the pot, the heat is transferred directly from the flame to the pot by conduction. A smaller flame will radiate heat to the pot but will also heat the air between the flame and the pot (by conduction) and the hot air will also transfer heat to the pot by conduction. Either way, heat moves from the bottom of the pot to the rest of the pot and the food inside by conduction.
What control how loud or soft sound is?
The size of the sound waves emitted
How do you make a musical Tesla coil?
Solid state coils are particularly well suited to audio modulation because of the very high level of control over the operation of the tesla system. There are many ways of modulating a SSTC (solid state tesla coil), the 2 most popular being AM (amplitude modulation) and what i will call "PRF Modulation". PRF stands for pulse repitition frequency. The reason these 2 modulations exist, is because there are 2 (actually more) distinct types of SSTC. Those that can produce a continuous spark output (that is, a flame like plasma that exists at 100% duty cycle) and those that make what appear to be a continuous spark, but are rather producing sparks at several hundred times per second with a rest between each spark event. The first (continuous) type of SSTC lends itself to audio modulation. Normally the output spark is a silent plasma flame. By modulating the amount of power put into the plasma flame, we can modulate the physical volume of the plasma. Modulating the size of the plasma will cause the expansion/relaxation of air surrounding the plasma, thus producing sound waves.
Parts of a Bunsen burner adjusted?
There are two adjustable parts on the Bunsen burner, the knob to control gas flow and the rotation of the collar to control air flow. The gas flow control, adjusts the size of the flame by controlling how much gas is burned. While the collar controls the intensity of the flame by controlling how completely the gas burns, more complete combustion the hotter the flame. These are the two parts to adjust a Bunsen burner, I hope I have answered your question.
How can you make the hottest flame on a Bunsen burner?
By increasing the size of the opening at the base, allowing more oxygen to the flame. The hottest flame is the blue flame.
How does adjusting the barrel on the Bunsen burner affects the flame?
The bottom of a Bunsen burner contains holes that allow air flow. When there is no air flow, the temperature of the flame will be hotter. With the holes wide open, the flame will not be as hot.
Parts of a Bunsen burner?
The parts of a Bunsen burner has collar,base.air hole and barrel. Collar : Adjust size of air hole Base: Support Bunsen Burner Air hole: Allow air to enter air hole Barrel:To ensure the flame is adjusted to a suitable position
How do you regulate the size of a flame when using a Bunsen Burner?

Why do you heat flammable liquid such as methanol with an electric heater rather than a Bunsen burner?
Two main reasons - one is that the bunsen burner flame is actually quite small in relation to the dimensions of the bottom of the beaker. If you take something that has a small surface area in relation to the size of the flame (for example a glass rod) that can be made to soften in a bunsen burner flame much more easily. The second reason is that the beaker or flask will generally contain something that you are trying to heat up or boil. So heat energy from the flame will initially transfer through the glass into that substance and be "used up" in bringing this liquid up to its boiling point,
Where does the air enter the Bunsen burner?
There is an opening at the bottom of the barrel above where the gas enters. There will be a valve or collar that changes the size of the opening.
What part of the burner is adjusted in changing the size or height of the flame?
The gas regulator if fitted, or the gas tap.
Why does closing the gas tap a little reduce the size of the flame?
Closing the gas tap a little reduces the amount of gas flowing into the burner. This causes a reduction in flame.
What happens to the flame size when the gas control valve is turned?
adjusts the size
What does the negative and positive sign mean on the butane lighters?
Moving a screw or control towards the + increases the size of the flame, the - sign decreases the flame size.
What happens to the color of the flame if you open the air mixture valve wide open?
The flame itself will get bigger/hotter, and the amount of 'blue' increases. Depending on the type of burner, it may or may not increase proportionately with the total flame size.
