Which of the following statement is correct regarding ignition temperature? |
It is the highest temperature at which a substance catches fire. It is the lowest temperature at which a substance catches fire. It is the lowest temperature at which a substance does not catch fire. It is the highest temperature at which a substance does not catch fire. |
It is the lowest temperature at which a substance catches fire. |
The correct answer is option 2. It is the lowest temperature at which a substance catches fire. The lowest temperature at which a substance catches fire is called its ignition temperature. For example, Kerosene oil and wood do not catch fire on their own at room temperature. If kerosene oil is heated a little, it will catch fire. But if the wood is heated a little, it would still not catch fire. It means that the ignition temperature of kerosene oil is lower than that of wood. |
