Question 1 of 27070

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

🔍 Key Concepts

• Spontaneous ignition happens when a material heats itself without an external flame or spark • How oxidation (like slow burning or rusting) can produce heat inside a material pile over time • Difference between latent heat processes (phase changes) and chemical reactions that release heat

💭 Think About

• Think about which option involves a chemical reaction that can continue inside a pile of material (like oily rags, coal, or grain) and slowly raises the temperature until it ignites on its own • Ask yourself which processes (expansion, sublimation, condensation, oxidation) are mainly about phase changes or volume changes versus about slow burning • Consider what commonly causes cargoes or stored materials to self-heat in confined spaces on ships

✅ Before You Answer

• Identify which choice is associated with slow combustion or rust-like reactions that give off heat over time • Eliminate any processes that primarily involve phase change (solid↔liquid↔gas) without a chemical reaction • Verify which process is known in fire prevention as a cause of spontaneous combustion in stowed materials
