🔍 Key Concepts

• Heat transfer methods in a fire (conduction, convection, radiation) • How hot gases and smoke move through a ship’s interior spaces • The role of stair towers and doors in vertical fire spread

💭 Think About

• Think about which method of heat transfer involves movement of hot gases or smoke through openings like doors and stairways. • Ask yourself: a stair tower is basically a vertical shaft—how does fire or heat most easily travel upward through such a space? • Consider which method of heat transfer doors can physically block just by being shut, versus what can still pass through a closed door.

✅ Before You Answer

• Identify which heat transfer method depends on air or fluid movement rather than direct contact or line-of-sight heating. • Decide which method is most responsible for carrying smoke and hot gases up stairwells on ships and in buildings. • Verify that the option you choose is something that a closed door can effectively limit or interrupt in a stair tower.
