3. Study why the flames of it are changing when the collar adjusted

APPARATUS AND MATERIALS:

THEORY:

1 Bunsen Burner1 Match

Gas from gas pipe

PROCEDURE:

OBSERVATION:By doing this lab the student will learn how to operate a bunsen burner safely. Also,

the student will explore and try to explain an apparent violation of the Law of Conservation of Matter. This is an inquiry lab in which students must design and carry out experiments to complete the objectives.

DATA AND RESULTS:

ANALYSIS AND INTERPRETATION:

CONCLUSION:

I there for conclude that the bunsen burner, named after and co-designed by Robert Bunsen in 1854, is a common laboratory instrument that produces a hot, sootless, non-luminous flame. The Bunsen Burner allows for precise regulation of the mixing of gas and oxygen in its central barrel before combustion, which ignites the flame. By manipulating the Bunsen burner, both the size and temperature of the flame can be controlled. Among other uses, the heat of a Bunsen burner flame can be used to create a convection current, which heats the space above the flame and lifts any particulates in the air up and away from the cooler air underneath it, keeping this work area sterile. Working with an open flame requires extra caution. Always remember to secure any loose hair, clothing, or accessories before lighting a Bunsen burner and to always have the proper safety equipment, like a fire extinguisher and/or a fire blanket, on hand. Taking the time to understand how to use a Bunsen burner and what safety equipment to have on hand will allow you to operate this useful laboratory tool with safety and confidence.
