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 to note of when using Bunsen burner?
dont burn things
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.
When you are not using a Bunsen burner but wish to leave the flame on you should always leave the air hole closed why?
It is less hot
What safety precautions should you take when using a Bunsen burner?
Bunsen burners are a fire hazard and should not be left unattended. However, accidents can occur even when the burner is off. Check the tubing connecting the gas line to the burner to be certain there are no cracks and it is secure. If the tubing is dislodged and the gas line valve is not off, gas will fill the room creating a potential explosion situation. This has happened. There are safer alternatives to the classic Bunsen burner. A Flame Boy or a Touch-o-matic burner eliminates the issue of a constant flame. A bacticinerator can be used to sterilize plating loops. There are also glass bead sterilizers that may be used.
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.

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.
How do you combine the Bunsen burner to the LP gas cylinder?
There will be a valve at the bottom of the Bunsen burner. Using a rubber tubing connect the valve to the regulator of the LPG cylinder.

Which metal can you boil from a Bunsen burner?
You can boil mercury from a Bunsen burner. Mercury has a low boiling point of 674 degrees Fahrenheit, making it possible to vaporize it using a Bunsen burner's high heat. However, it's important to note that working with mercury can be hazardous, so proper safety precautions should be taken.
Why tip a Bunsen burner at an angle when using?
contaminates will be less likely to drip inside the burner this way
How much time is required to melt sodium chloride using Bunsen burner?
The time it takes to melt sodium chloride using a Bunsen burner can vary based on factors such as the heat intensity of the burner, the amount of sodium chloride being melted, and the starting temperature of the salt. Generally, it may take a few minutes to melt sodium chloride completely using a Bunsen burner.
When you are not using a Bunsen burner but wish to leave the flame on you should always leave the air hole closed why?
