Explanation:

step by step ..

Ignition temperature above room temperature

Solution: Ignition temperature is the lowest temperature at which a substance catches fire. We know, if the temperature of the fuel will be lower than the room temperature, then it can catch fire very easily which will be hazardous. So, for an ideal or a good fuel, the ignition temperature should be higher than room temperature.

Answer 2

The correct option regarding the IGNITION TEMPERATURE of a good/ideal fuel is

(1) Ignition temperature should be above room temperature.

Reasons Why the ignition temperature of a good fuel should be above the room temperature:

1. The temperature at which a fuel catches fire is known as the ignition temperature.
2. It is the minimum temperature.
3. If a fuel kept in a room has an ignition temperature that is lower than the rooms' temperature, it will easily catch fire which can be hazardous.
4. An ideal or good fuel should have an ignition temperature above the room temperature, and it cannot be even equal to room temperature because that might also lead the fuel to catch fire easily.
5. Normal room temperature is typically equal to 20°C which is very lower than 100°C, hence it can be understood that an ideal fuel cannot have an ignition temperature equal to 100° C.
6. although some fuel has self or auto-ignition temperature higher than that.
7. For example, Kerosene has an auto-ignition temperature of around 220° C.
