The Bunsen burner is the main source of heat in a school laboratory and it uses gas.

Parts of a Bunsen burner are

2. Collar: A rotatable part at the base of the barrel that controls the air supply by opening or closing the air holes.
3. Air holes: Openings near the base of the barrel that allow air to mix with gas for combustion.
4. Gas inlet: The point where gas enters the burner, connected to a gas source via a rubber hose.
5. Base: A sturdy, flat structure that provides stability to the burner.
6. Gas valve: A knob or tap used to regulate the flow of gas entering the burner.
7. Rubber hose: A flexible tube that connects the gas source to the gas inlet of the burner.
8. Flame: The result of igniting the gas-air mixture at the top of the barrel, adjustable based on the air supply.
