Which property of kerosene makes it suitable for use in lamps during combustion analysis experiments?

• A. It has a high ignition temperature, making it safe to handle.
• B. It is non-flammable and does not support combustion.
• C. It produces large amounts of soot during combustion.
• D. It burns easily and produces a steady flame.

Answer: (D)

Verified step by step guidance

1. Understand the context: Kerosene is commonly used as a fuel in lamps and combustion experiments because of its combustion properties.
2. Recall the key properties of kerosene related to combustion: it should ignite easily, burn steadily, and produce a consistent flame without excessive soot or smoke.
3. Analyze the options given: a high ignition temperature would make it harder to ignite, being non-flammable means it cannot burn, and producing large amounts of soot is undesirable for clean combustion.
4. Identify the correct property: kerosene burns easily and produces a steady flame, which is ideal for controlled combustion analysis.
5. Conclude that the suitability of kerosene in lamps during combustion experiments is due to its ability to ignite readily and maintain a steady, clean flame.
