To prevent flame impingement on the vessel being heated, which could damage the vessel. A flame cannot pass through a gauze (or screen). as a proof you could set up a bunsen burner beneath a wire gauze. Turn the gas on and ignite the gas above the gauze. you will notice the flame will stay above the gauze. If you ignite the flame beneath the gauze and lower the gauze into the flame, the flame will not pass above the gauze. Yet, if you light both below and above the gauze you will have flame on both sides. Indicating that flames impinging on the gauze do not burn the gas completely and the gas will pass through the gauze.
What else can I help you with?
Where should you hold heating objects in the heating flame when heating them with a Bunsen burner?
Hold heating objects just above the blue inner cone of the Bunsen burner flame. This is the hottest part of the flame and will provide the most efficient heating. Be cautious not to hold the object directly in the tip of the inner cone, as it may cause overheating or combustion.
What is the color of flame produced by burning magnesium?

If you lift the glass tumbler which is placed over a burning candle to 1cm height what hapens?
Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
Why does the Bunsen burner have two flames?
The Bunsen burner has two flames because the inner blue flame is the hottest part of the flame used for heating, while the outer yellow flame provides a stable base and helps to mix in air for complete combustion. This dual flame design allows for precise control of temperature and ensures efficient burning of the fuel gas.
What happens to evaporating dish when placed to a non-luminous flame?
When an evaporating dish is placed over a non-luminous flame, the organic substances in the dish will burn, leaving behind inorganic residues like ash. The heating process will also drive off any volatile gases or liquids present in the dish.
When heating a substance over a bunsen burner where should the object be placed for most efficient heating?
The object should be placed at the tip of the inner blue cone of the bunsen burner flame. This is the hottest part of the flame and will provide the most efficient heating to the substance. Adjust the height of the object as needed to maintain the best heating.
When heating a substance over a Bunsen burner where should the object be placed for the most efficient heating?
The object should be placed in the hottest part of the flame, which is the tip of the inner blue cone. This is where the flame burns the hottest and will provide the most efficient heating. Be sure to adjust the height of the object to control the temperature and prevent overheating.

What kind of flame is recommended in burning in Bunsen burner?
A blue, non-luminous flame is recommended for burning in a Bunsen burner. This flame is efficient for heating as it has a high temperature and is well-suited for various laboratory applications. Adjusting the air inlet controls on the Bunsen burner can help achieve the desired flame type.
Describe and explain what happens to the piece of wooden splint when it is placed in the different parts of the Bunsen flame?
When a wooden splint is placed in the outer part of the Bunsen flame, it burns with a smoky flame due to incomplete combustion. When placed in the inner blue cone of the flame, it burns with a clean, non-smoky flame due to complete combustion of the wood. The inner blue cone is the hottest part of the flame, which allows for more efficient burning.

Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
