Today, in Making Waves hurumanu. We first looked at Science Equipments, and then the Bunsen Burner. We first, we had to label the Bunsen Burner parts.A Bunsen burner is a common piece of laboratory equipment. It is one of the most dangerous.
We had to do an experiment using a Bunsen burner.
Lighting a Bunsen BurnerAim: To correctly light a Bunsen burner.
Equipment:
- Bunsen burner
- Heatproof mat
- Lighter
Method:
- Place the heatproof mat on your workbench.
- Connect the Bunsen burner to the gas outlet.
- Turn the collar so that the air hole is closed.
- Light a lighter and hold it 2-3 cm above the nozzle of the Bunsen burner.
- Turn the gas on at the top.
a) Describe the colour of the Bunsen burner. Blue - Extremely Hot, Orange - Hot
b) Is the flame producing any noise? No
c) Is it producing any smoke or soot? Yes, a little bit
6. Carefully move the collar so that the air hole is now open.
d) Describe the colour of the Bunsen flame. Orange
e) Is the flame producing any noise? No
f) Is it producing any smoke or soot? Yes, a little bit
g) Is the Bunsen flame you described in a) more visible than the flame you described in d)? No, because in a), the colour of the Bunsen burner was blue and orange, and when the air hole is open, it is orange.
h) If you were going to leave your Bunsen burner unattended should the air be open or closed? Justify your answer.
c) Is it producing any smoke or soot? Yes, a little bit
