Why is it no use trying to heat something too close to the top of the chimney of the Bunsen burner?
Heating something too close to the top of the Bunsen burner can cause incomplete combustion as the flame might not get enough oxygen to burn efficiently. This can lead to the production of soot or carbon monoxide. It's best to position the object slightly above the top of the flame to ensure proper heating.

Why is it no use trying to heat something too close to the opening chimney of a Bunsen burner?
Heating something too close to the opening chimney of a Bunsen burner can result in inefficient heating due to reduced air flow. The intense heat from the burner can also cause overheating and possible combustion of the sample or chemicals being heated. It is best to maintain an appropriate distance to ensure proper heating and prevent accidents.
Why is it no use trying to heat something too close to the opening of the chimney on a bunsen burner?
Heating something too close to the opening of the chimney on a Bunsen burner can lead to incomplete combustion as there is not enough oxygen available for the process. This can cause production of toxic fumes or soot, resulting in an inefficient heating process. Placing the object further away allows for better air flow and ensures complete combustion.
When can friction be unuseful?
Friction can be unuseful when trying to achieve smooth motion in machines or when trying to move heavy objects. It can generate heat and cause wear and tear, leading to inefficiencies and increased energy consumption. In certain applications, such as in some precision instruments or machinery, reducing friction is desirable.
Could not unturned the stone?
This phrase means that every possible effort has been made to explore or investigate a situation or problem. It suggests thoroughness in searching for a solution or in trying to understand something.
Why do ghost touch you?
There is no scientific evidence supporting the existence of ghosts or their ability to physically touch individuals. Reports of ghostly encounters are subjective experiences influenced by belief systems, emotions, and environmental factors.

because it wont work!
How was a Bunsen burner made?
The Bunsen burner was the result of a building lighting approach that Robert Bunsen was trying to implement in a new laboratory building he was entrusted to design for the University of Heidelberg. The building had a gas supply which was thought to be useful for creating heating and lighting capabilities. The Bunsen burner was to regulate this gas supply for these purposes.
What happens when you are trying to separate salt water and you place it in the oven without putting it under the Bunsen burner first?
Splashing may occur.
What is a base of Bunsen burner?
You're probably trying to make this question much more difficult than it actually is. The base is simply the bottom part that keeps it from tipping over.
What is wrong with using a piece of burning paper to light a Bunsen?
Using a piece of burning paper could potentially cause the flames to travel back to your hand when trying to light a Bunsen burner. It is safer to use a mechanical striker or a lighter designed for lighting Bunsen burners to prevent accidents.
Why it is necessary to hold the neck of the tubes in the flame of Bunsen burner?
Experience, or indeed a little foresight shows that holding it anywhere else will result in getting your fingers or tongs burnt in the flame. Usually the thing you are trying to heat is at the bottom of the tube and the neck is farthest away from that.
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,
What two elements did robert Bunsen discover?
Robert Bunsen was born on the 30th of March 1811 in Gottingen, Germany. Robert was the youngest of four sons, he was one of the most appreciated scientists of his generation. He was a great teacher, dedicated to his students. He liked to work quietly in his laboratory, continuing to improve his science with useful discoveries. He never married. Bunsen started studying in chemistry, and received his university degree at 19 years of age. After graduation, he traveled throughout Europe to study engineering, geology and chemistry. One of his first discoveries was in physiological chemistry when he discovered the iron oxide hydrate as a medicine for arsenic poisoning. Bunsen's discoveries added to his scientific knowledge because he would make mistakes trying to invent or create something new and he would make mistakes and that will help him learn more about what he was trying to create. Robert retired at the age of 78 and was 88 years old when he died on the 16th of August 1899,
Do you have a CD burner?
I do, thanks for asking. No, you can't borrow it. If you're trying to determine if YOU have a CD burner, usually looking at the front of it will tell you.
What are 4 facts about the Bunsen Burner?
The Bunsen burner is such a familiar fixture of chemistry labs that its reputation reaches students even before they enter the classroom. As an icon of science, it permeates popular culture. But where did the Bunsen burner come from? Who invented it? You might hope to chuckle at the absurdly obvious: "why, Bunsen, of course!" But a brief foray into history may be warranted before placing too significant a wager on the "obvious."Robert Bunsen, whose name we associate with the burner, was a 19th-century German chemist of some renown. He worked on explosive organic arsenic compounds--leading to the loss of one eye--and, later, on gases from volcanoes, geysers and blast furnaces. With Kirchoff he contributed to our understanding of the meaning of spectra lines. (He also gained note for not bathing--one woman of polite society remarked that Bunsen was so charming that she would like to kiss him, but she would have to wash him first.) Bunsen invented many bits of laboratory apparatus: the spectroscope, the carbon-pole battery, an ice calorimeter and vapor calorimeter, the thermopile, and the filter pump--but not, as one might imagine, the gas burner that bears his name. Rather, the "Bunsen" burner was developed by Bunsen's laboratory assistant, Peter Desdega. Desdega himself likely borrowed from earlier designs by Aimé Argand and Michael Faraday. So why does Bunsen get the implicit credit? --And why do we know so little about Desdega that we cannot add much to his story?"Bunsen's" burner illustrates an important dimension of science frequently omitted in teaching about science: professional credit. Eponymous laws and labels--whose names reflect their discoverers--appear throughout science: Snell's law of refraction, Gay-Lussac's law of gases, the Hardy-Weinberg model of population genetics, the volt (named for Alexander Volta), etc. The naming of laws for their discoverers seems appropriate for honoring the scientists--and the human names are handy for reminding students that science is done by real persons. But in this system, one person and only one person gets all the credit. Focusing on great individuals can hide the collective nature of science, especially the role of technicians such as Desdega. How do we distribute the credit where appropriate?The great Isaac Newton is frequently quoted for expressing the humbling effect of the collective effort in science: "If I have seen further," he once professed, "it is by standing on the shoulders of giants." Newton's claim, we now know, betrayed a false modesty. Newton's bitter priority dispute with Leibniz over the invention of the calculus, in particular, bears witness to his ambition and obsession with prestige--and his political maneuvers in trying to achieve it. In that case, at least, Newton tried to further his own stature "by standing on the claims of competitors." In similar ways, perhaps, the contributions of technical workers often get buried when we allow theoretical discoveries of the work of their masters to overshadow them. Bunsen's burner--or perhaps the Desdega burner--is a notable example.The story of the Petri dish is an interesting exception--while at the same time underscoring the general pattern of invisible technicians. Julius Richard Petri (1852-1921) worked for the master of "germ theory" in Germany in the late 1800s, Robert Koch (1843-1910; pronounced as a gutteral "coke"). Initially, bacteria were cultured in liquid broth--a practice captured in our famous images of experiments on spontaneous generation. But Koch saw the advantage of growing bacteria on a solid medium instead. By spreading out mixtures of microorganisms on a solid surface, he could separate individual types in isolated colonies. With pure colonies, he could investigate the effects of each bacterium. The method allowed Koch to identify the specific organisms that cause tuberculosis, cholera, diptheria, among many other diseases--and then to develop vaccines.
