Question

Identify the correct option regarding the ignition temperature of an ideal fuel.

• A. Ignition temperature should be below room temperature.
• B. Ignition temperature should be above room temperature.
• C. Ignition temperature should be equal to room temperature.
• D. Ignition temperature should be equal to ${100}^{\circ }$C.

Answer 1

The correct option is B Ignition temperature should be above room temperature.

Ignition temperature is the lowest temperature at which a substance catches fire. If the ignition temperature of a fuel is lower than the room temperature, then it can catch fire very easily.
Therefore for an ideal fuel, the ignition temperature should be higher than the room temperature.
