The exercises focus on testing knowledge about combustion, the properties of fuels, and the characteristics of flames. They include fill-in-the-blank questions, comparisons, and problem-solving tasks, encouraging students to apply what they have learned in practical scenarios.
The section provides a series of exercises designed to reinforce key concepts about combustion and flame. The exercises contain questions that address various aspects, including the conditions for combustion, the properties of fuels, and the differences between various combustion types. Through fill-in-the-blank activities, comparison of fuels, and short reflection questions, students consolidate their understanding of essential concepts such as ignition temperature, fuel efficiency, and the role of oxygen in the combustion process. The exercises also encourage critical thinking and application of knowledge, laying a strong groundwork for practical understanding and observation of combustion phenomena in everyday contexts.
Fuel: A substance that can burn to produce energy.
Combustion: The process of burning that gives off heat and light.
Ignition Temperature: The lowest temperature at which a fuel will ignite.
Inflammable: A term describing materials that ignite easily.
Fire needs fuel that's dry and light, with oxygen to flare up bright!
Once in a forest, a small spark met dry leaves and said, 'Let's ignite!' And with air around, a fire danced into the night.
Remember 'FOH' for Fire: Fuel, Oxygen, Heat!
Candle wax is a common fuel that burns to produce light and heat.
Dry leaves catch fire easily due to their low ignition temperature compared to wet leaves.
