What colour is a Bunsen burner flame?
The most efficient flame that a Bunsen burner can produce should be pale light blue, and almost invisible. A yellow or luminous flame should be avoided as it isn't as hot as the blue flame and leaves sut.
Why is it safer to evaporate alcohol using an infra red heater rather than using a Bunsen burner?
The Bunsen burner uses an ope flame, making it easier for the alcohol to ignite.
How do you control the height of the flame on a bunsen burner?
The height of the flame on a Bunsen burner can be controlled by adjusting the gas supply using the gas tap. Turning the gas tap to increase the gas flow will raise the flame height, while decreasing the gas flow will lower the flame. Positioning the collar on the burner can also help control the air-to-gas ratio and influence the flame height.
What is appearance of a flame that is used for heating?
luminous
Steps how to use a Bunsen burner?
that the gas is connected properly. 1.check that its not leaking or damaged becoz we are using highly flammable substance 2. wear lab courts before using it 3.one should not try to handle it when it is in use
What colour should the flame be on the Bunsen burner when you are not using it?
The flame on a Bunsen burner should be blue when not in use. If the flame is yellow, it may indicate a problem with the burner, such as not enough air mixing with the gas, which can be a safety hazard.
What kind of flame takes longer time to boil water using Bunsen burner?
A yellow flame would take longer to boil water using a Bunsen burner compared to a blue flame. This is because the yellow flame is cooler and provides less heat energy for boiling water.
Why is a Bunsen burner better than using a candle or a fire?
Bunsen burners are preferred over candles or fires because the Bunsen burner produces a much higher temperature (noted by the blue flame) and it is much easier to contain/control a Bunsen Burner flame.
What colour is a Bunsen burner flame?

Which setting gives the hottest flame when using a Bunsen burner?
The blue flame is the hottest... The yellow one is called a safety flame and if you swipe your hand qckly through the safety flame, it won't burn... If you do it quick enough
What is a Bunsen burner and what is its function?
The bunsen burner is used to heat items for experiments using a controllable temperature flame and surface area at which the heat is applied to the vessel.
How can you make a Bunsen burner hotter?
By using the correct ratio of oxygen and fuel mixture. Opening the air hole in the Bunsen burner increase the oxygen which helps the flame burner hotter .
Why is it safer to evaporate alcohol using an infra red heater rather than using a Bunsen burner?
The Bunsen burner uses an ope flame, making it easier for the alcohol to ignite.
What is the maximum temperatures that can be achieved using a blue flame on a Bunsen burner?
Maximum temperature is 16000C

Positioning the collar on the burner can also help control the air-to-gas ratio and influence the flame height.
Which elements may be excited using a Bunsen burner flame?
Metals such as sodium, potassium, calcium, and copper can be excited using a Bunsen burner flame to emit characteristic colors. This technique is commonly used in flame tests to identify different elements based on the color of light they emit when heated.
Why do you use the blue flame while using a Bunsen burner?
The blue flame of a Bunsen burner is the hottest part of the flame, making it ideal for heating and sterilizing purposes in a laboratory setting. The blue flame indicates complete combustion of the gas, leading to a cleaner and more efficient burn.
