What is the function of the collar of a Bunsen burner?
The collar regulates the amount of air which mixes with the fuel gas before it is burned. If the hole in the collar is not lined up with the hole in the bunsen stem, the fuel does most of its mixing with air at the top of the burner. This makes burning inefficient and the flame is cool. When the two holes line up, air is pre-mixed with the fuel, burning is much more efficient and the flame is as hot as possible.the collar of a bunsen burner is the part which doesnt get hot and you can twist it to close or open the air hole.Turning the collar opens and closes the air-hole which allows a controlled amount of oxygen to mix with the gas. The amount of air mixed in determines the colour and heat of the flame.The collar controls the amount of air and thus oxygen that can reach the methane gas inside the burner. With the hole closed there is no additional oxygen to mix with the methane and so we have a yellow flame. Opening the hole allows oxygen to mix with the methane so it burns at a higher temperature and with a blue flame.The collar on the Bunsen burner is to allocate as much oxygen as desired from the atmosphere into the Bunsen burner. The more oxygen in the Bunsen burner, the bluer or clearer the flame is. It is much hotter when in the blue flame.
What is the meaning of tripod in science?
A tri-pod - is a metal frame suported on three legs (hence the name) - that is used to suspend a beaker or flask above a bunsen burner. It allows the flame to reach the beaker, while keeping it off the frame itself.
A boy kicks a ball vertically upwards with an initial velocity of 12m/s. Calculate the time taken by the ball to reach the maximum hight and the maximum, height reached by the ball?
The time taken by the ball to reach the maximum height is 1 second. The maximum height reached by the ball is 36 meters.
If you put somthing in water how long does it take to get to the waters temperature?
The temperature of the water and the something will reach an equillibrium somewhere between the two and eventually both will reach room temperature. Time depends on the temperature and mass of the something and the temperature and volume of the water.
What is the maximum temperature a fire can reach?
Thomething about 1200 and 1500 degree, its a very conced degree here in Celcius. If you see a fire from gas with it´s blue flame, it has exactly the temperature from about, if you see a yellow flame it is also exactly one spezial degree. That is that astonishing it never various . . . and does not come over 2000
Is the temperature of Bunsen burner flame 750 to 950 degree celsius?
No. The lowest temperature , with oxygen closed off and a yellow flame , is about 1000 degrees Celsius. With oxgen feed open temperature of the flame can reach 1300 degrees.
Does the Bunsen burner flame roar or burn quietly?
A Bunsen burner flame can both roar and burn quietly, by allowing more oxygen to reach the flame by opening a valve it will roar, by closing the valve the flame will flicker
Which is more useful between an alcohol lamp and Bunsen burner?
A Bunsen Burner is more useful because its flame is more controllable , it can reach a roaring blue flame, and its features such as the collar and the gas controller makes it safer.
What is the use of mecker burner?
It's pretty much the same as a Bunsen burner, so it's used to heat samples in a laboratory. It can reach higher temperatures than a Bunsen, and its structure is slightly different; the base of the flame has a larger radius.
What is a burner used for in the lab?
A Bunsen burner has several uses in the lab, the most obvious being its use as a heating element. Bunsen burners can reach a temperature of up to 1000 degrees Celsius, which is hot enough to melt silver. Bunsen burners are also useful for initiating combustion, a common experiment being the burning of table sugar in a test tube to yield carbon dioxide, water and ash. In biochemistry and microbiology labs Bunsen burners are used to sterilize equipment.
A Bunsen burner burns with the hottest flame when its hole is fully open because this allows plenty of gas from the air to reach the flame What is this gas?
Oxygen
How does an airplane reach its fastest speed?
Augmented maximum mechanism or in simple term after burner is incorporated to high speeds.
How do you correct a yellow flame on a Bunsen burner?
The flame of a Bunsen burner can potentially reach up to 1100-1200 degrees Celsius. On the bottom of the burner there is a ring which open and closes the way of oxygen from air to the gas. When the ring is open the oxygen flows to the gas and the flame becomes blue ( this is hotter flame :) if you close the ring the burning will be without oxygen and the flame will by yellow-red ( this one is cooler ). So the temp. of the Bunsen burner depends on the ring. If i remember correcty the tip of the blue flame is the hottest ( i think but not sure 1600 degrees Celsius).

Can a burner on an electric store reach 400 degrees?
An electric burner normally can reach max temperatures of 800 degrees Fahrenheit.
Is Boiling is the maximum temperature a substance can reach?
No. Once the substance crosses into steam the steam temperature can rise much higher than boiling.
What temperature does pure water reach maximum density?
4 degrees Celsius
