What is a tirrill?
In the context of chemistry, this is likely to refer to a type of burner. The difference between a Bunsen burner and a Tirrill burner has to do with how the air flow is regulated ... a Bunsen burner usually has slits at the base of the barrel to admit air, while in a Tirrill burner the airflow is controlled by means of a needle valve. Burners in a real chemistry lab are actually more likely to be of the Tirrill type than the Bunsen type, since the needle valve allows better regulation of the air-gas mixture and therefore a steadier more reliable flame. There are some other modifications as well (the most common one being the Meker, which is the one with the "big head" that has a grid inside it, which spreads the heat more evenly). I've also seen a kind with horizontal slits where incoming air is regulated by screwing the entire barrel up and down (this is less common, as the barrel may become uncomfortably warm to touch, though it usually takes some time for this to happen and the adjustment of the air/gas mix usually happens immediately after the burner is ignited). I don't know if that type has an official name, or if so what it is.
What happen ton sulphar when slightly heated in test tube by a Bunsen burner?
When sulphur is heated in the test tube in the absence of air the sulphur will break down and form a red-brown liquid. If oxygen comes into play sulphur dioxide is produced, however you should not that sulphur dioxide is a highly toxic gas and should only be produced in small amounts under a fume hood.
What is makes the flame luminous?
How: by opening up the air hole on a Bunsen burner after it is turned on.........What: Some atoms or molecules are not luminous when hot. They emit light outside the spectrum we can see, like CO2 emits infrared. Others only emit a faint color in the flame.The non-luminous is made when there is a complete combustion or complete burning process. It happens when there is more than the enough oxygen in the surroundings or in the place where the process will happen.
What happen to the perfume after 15 minutes?
The particles will diffuse and eventually spread across the room.
If a ice cube is left on a table for ten minutes what will happen to it?
it takes about 3-4 mins
When did mr Bunsen burner live?
did not happen
What will happen when the Bunsen burner strikes back?
You have to turn off the gas tap immediately.
What will happen if you place a flammable substance near a Bunsen burner?
If placed close enough, the flammable substance will burst into flames.
When did After Burner happen?
After Burner happened in 1987.
When did After Burner II happen?
After Burner II happened in 1987.
When did After Burner III happen?
After Burner III happened in 1992.
Can you measure the temperature of a flame of a Bunsen burner using a thermometer?
Yes, and No. You will get an inaccurate number since of air temperature and a few variables, but it will be relatively close. I do not recommend this, because a few things may happen, and even some I do not even know of. The thermometer will get hot and melt. Or explode. And many other things can happen.

What can happen if you play near a lighted gas burner?
Then you might hurt yourself
What would happen if you turned on the gas and let it run for a while before lighting a match to light a Bunsen burner?
Depending on what gas it is, it could be heavier than air, which would mean it could "pool" around in the room and if ignited could explode or cause a huge fireball thereby killing or injuring others. Dont do it.
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.
