Why is it no use trying to heat something too close to the opening chimney of a Bunsen burner?
because it wont work!
When can friction be unuseful?
This could be harmful when you are trying to move something heavy and it doesn't move.
Why do ghost touch you?
Sometimes to get energy from you, maybe they like you or they're trying to protect you from something in the present or future, or they are just trying to kill you in some shape or form.
Why did Einstein say If I knew what I was doing I wouldn't have done it?
What would be the point of trying to invent, discover, or create something if you knew what you were doing.
What does it means to clarify?
To clarify something means to explain or back up your information so that one can understand more better. Whenever you clarify something you should add more details so that what you're trying to say makes more sense.

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.
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,
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.
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.
Put something on the back burner?
This isn't a question as such because it has no context.However, if someone is said to put something on the back burner - it means that they intend to, or have, put something off until another time.Example: I am going to put my revision on the back burner- means I am going to delay my revision.
If the spce heater flame goes out how long should you wait before trying to restart the heater?
30 minutes when the burner has cooled
