🔍 Key Concepts

• Conduction vs. convection vs. radiation vs. flame impingement – know how each moves heat on a ship. • Look closely at Figure 1 air/heat flow arrows from the fire area toward compartment A, then think about how B is arranged in relation to A. • Remember that convection uses moving hot gases, while conduction uses solid metal, and radiation is line‑of‑sight heat.

💭 Think About

• In Figure 1, is compartment B in the direct path of flames or hot gases, or is it separated by a bulkhead/deck from the shown flow? • If the fire starts where the red arrows originate, what must happen physically for B to heat up enough to ignite – does heat have to travel through steel, through air movement, or by direct flame contact? • Would someone standing in B in Figure 1 see flames or just feel heat building through a boundary or from above/below? What does that suggest about the heat‑transfer method?

✅ Before You Answer

• Verify how B is separated from the initial fire space in Figure 1 (solid boundary vs. open passage). • Check whether any arrows actually enter B in Figure 1, or if they only reach A and then must cross into B another way. • Match what you see to the textbook definitions: conduction = through metal, convection = with smoke/hot air flow, radiation = line‑of‑sight heat, impingement = flames directly hitting a surface.
