Question

The __________ temperature at which a substance catches fire is called its __________ temperature.

• A. lowest
• B. Ignition

Answer 1

Explanation:

1. The lowest temperature at which a substance ignites is called the ignition temperature.
2. Ignition temperature is an important property of fuels. The combustion process is only sustainable above the ignition temperature.
3. Fuels that have higher volatile substances generally tend to have a lower ignition temperature
4. The ignition temperature depends on several factors such as oxygen, partial pressure, particle size, heating rate, and the thermal environment of the particles.

Hence, the lowest temperature at which a substance catches fire is called its ignition temperature.
