Q

Through which of the listed processes is sufficient heat produced to cause spontaneous ignition?

🔍 Key Concepts

• Spontaneous ignition and how heat can build up inside materials over time • Difference between simple decay (rotting) and chemical reactions that release heat • Role of oxygen in certain slow, continuous reactions in cargoes like coal, oily rags, or grain

💭 Think About

• Which of these processes is most closely associated with slow, continuous heat release inside a material, even without an external flame? • Think about cargoes like oily rags, coal, cotton waste, or damp grain: what kind of internal process makes them slowly get hotter until they may catch fire? • Which option specifically refers to a chemical reaction rather than just biological decay or physical mixing?

✅ Before You Answer

• Identify which option involves a chemical combination that naturally gives off heat over time • Ask: does this process require oxygen from the air, or does it occur without oxygen? How does that affect heat buildup? • Eliminate any options that mainly describe rotting or physical air movement rather than a heat‑producing chemical reaction
