Convection spreads a fire by __________.

Question 1 of 27070

Convection spreads a fire by __________.

🔍 Key Concepts

• Three methods of heat transfer in fires: conduction, convection, radiation • Behavior of hot gases and smoke inside compartments and ducting • How fires can spread without direct flame contact

💭 Think About

• Which choice describes hot gases or vapors MOVING from one place to another and carrying heat with them? • Which options actually describe other heat transfer methods (conduction or radiation) instead of convection? • Think about what happens to smoke and hot air when a fire starts in a closed room with an air duct or open door.

✅ Before You Answer

• Identify which option involves movement of a heated fluid (gas or liquid) carrying heat along with it. • Eliminate any answer that sounds like heat traveling through solid metal (that is conduction, not convection). • Eliminate any answer that sounds like heat traveling across empty space (that is radiation, not convection).
