A roaring flame in a Bunsen burner experiment is used initially to provide a high temperature and ensure rapid heating of the sample or substance being tested. This type of flame, which has a bright, blue color, indicates complete combustion and efficient heat transfer. It helps achieve the desired reaction or change quickly before switching to a more controlled flame for precise experiments.
The Bunsen burner was first invented by a British physicist and chemist called Michael Faraday in the early 19th century. It was than improved by a famous German chemist called Robert Bunsen in 1850. The second Bunsen burner was now safer, easier and more efficient and has an 'air hole' so you could change the flame from a safety flame (the yellow one) to a efficient flame (the blue one).
To turn off a Bunsen burner, first close the air hole at the base of the burner by turning the metal collar clockwise until it's fully closed. Then turn the gas knob on the burner clockwise until it stops to shut off the gas supply. Let the burner cool down before handling it.
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.
The screw lock in a Bunsen burner is used to control the airflow entering the burner. By adjusting the screw lock, you can regulate the amount of oxygen mixing with the gas, which in turn controls the size and type of flame produced by the burner.
You havesome options to get this done. The first is to set up a tripod with some wire gause across the top and place a Bunsen burner underneath, place the beaker on top and it will heat it. A much better way to do this is to use a hotplate and a magnetic stirrer, these hotplates are designed to got to specific temperatures. For round bottomed flasks an oil bath is put on top of the hotplate and the flask clamped into the oil and a magnetic stirrer placed in the oil bath, the round bottomed flask is clamped in place with a retort stand and clamp.
Peter Desaga constructed the first Bunsen burner.
The Bunsen burner was first introduced in the 1850s by German chemist Robert Bunsen and his laboratory assistant, Peter Desaga. However, the exact date of when the first Bunsen burner was sold is not well documented.
The correct sequence of steps for lighting a Bunsen burner is: B. Open the gas adjustment at the base of the Bunsen burner first, followed by C. Connect the gas supply. Finally, A. Apply the spark above the barrel of the Bunsen burner to ignite the gas.
The first prototype of the Bunsen burner was made by Robert Wilhelm Bunsen, a German chemist, in the 1850s. He collaborated with his laboratory assistant, Peter Desaga, to develop the device for more controlled combustion in their experiments.
Its first letter is B
blah blah blah

To put out a Bunsen burner, simply close the air vent to cut off the oxygen supply first, then turn off the gas supply using the valve on the burner. Never use water to extinguish a Bunsen burner as this can spread the flame.

To ignite a Bunsen burner, first ensure the air hole at the bottom is open. Then, use a striker or match to light the gas coming out of the burner. Adjust the air hole and gas flow to achieve the desired flame.
