Year 7 - Topic 1 - Bunsen Burner Diagram Quiz

Bunsen Burner Components

• Flame (Outer Cone)

  • The outer cone of the flame is where complete combustion occurs, producing a hotter and non-luminous flame.

• Flames (Inner Cone)

  • The inner cone is the hottest part of the flame, typically characterized by a blue color due to efficient and complete combustion of gas.

• Barrel or Chimney

  • The vertical tube that connects the flame to the gas source, facilitating gas and air mixing for combustion.

• Collar

  • Adjustable component that regulates the amount of air mixed with gas, affecting the flame type and temperature.

• Base

  • The sturdy support structure that stabilizes the Bunsen burner and prevents tipping during use.

• Rubber Tubing

  • Flexible connector that transports gas from the gas source to the burner, essential for safe and effective operation.

• Air Hole

  • An opening located on the barrel that allows air to enter and mix with the gas, critically influencing flame characteristics.

• Gas Valve

  • Controls the flow of gas into the burner; adjusting this valve alters the flame's size and intensity.

• Heat Proof Surface

  • A resistant surface under the Bunsen burner to protect the lab bench from heat damage during experiments.
