Question 1 of 27070

If a cargo of kerosene were considered "too lean" to explode, then it must be __________.

🔍 Key Concepts

• flammable (explosive) range of a vapor-air mixture • difference between too rich and too lean mixtures for combustion/explosion • relationship of the terms below LEL (lower explosive limit) and above UEL (upper explosive limit)

💭 Think About

• Think about what happens when there is not enough vapor (fuel) in the air for an explosion to occur. Is that called too rich or too lean? • Visualize the explosive range as a band between two limits. Ask yourself: where would the mixture be if it is too lean—before that band, inside it, or beyond it? • Recall: when a mixture is capable of exploding, is it inside the explosive range or outside it?

✅ Before You Answer

• Identify which side of the explosive range corresponds to "too lean" (insufficient fuel vapor). • Remember that within the explosive range is where vapors can actually ignite and explode under the right conditions. • Confirm whether "too rich" (too much vapor) and "too lean" (too little vapor) lie on opposite sides of the explosive range.
