Chapter Name: Combustion, Fuels and Flames
Activity Name: Observing the behavior of different solid fuels in Combustion, Fuels and Flames
In this experiment, various solid fuels are burned one by one using a spirit lamp. The time taken for each fuel to catch fire and the nature of their combustion are observed and recorded.
- Domestic gas (liquefied petroleum gas or LPG)
- Magnesium ribbon
- Cakes of cow-dung
- Wick of the oil lamp
- Wick of the kerosene stove
- Spirit lamp
Step by Step Procedure:
- Collect all the mentioned solid fuels and arrange them for the experiment.
- Set up the spirit lamp.
- Take each fuel sample one by one and attempt to burn it using the spirit lamp.
- Note the time it takes for each fuel to catch fire and observe how they burn (e.g., the color and intensity of the flame).
- Record your observations in a table.
- Note the time taken for each fuel to catch fire.
- Observe the nature of the flame produced by each fuel during combustion.
- Perform the experiment in a well-ventilated area to avoid the accumulation of combustion byproducts.
- Handle the spirit lamp and fuels with care to prevent accidents.
- Keep a fire extinguisher or a container of water nearby as a safety measure.
- Do not touch the burning fuels or spirit lamp during the experiment.
Lesson Learnt from Experiment:
- Different solid fuels have different ignition times and burn characteristics.
- Fuels that can be vaporized easily tend to catch fire quickly, while those that cannot be vaporized do not produce flames.
- Some materials burn with flames, while others may burn without visible flames.
