Conduction requires touching something hot, radiation doesn't. Both answers are correct. Conduction is faster, radiation is slower. 2 / 20 What are the three major types of heat transfer? Convection, Conduction, Nuclear Convection, Conduction, Radiation Convection, Radiation, Atomic Conduction, Radiation, Chain Reaction 3 / 20 What does fire give off that makes us feel warm? Sound energy Light energy Wind energy Heat energy 4 / 20 What are examples of materials that transfer heat well? Steel Iron Styrofoam Gold 5 / 20 What is a natural type of convection? The sun directly touching the ground to transfer heat. The heat waves from the sun heating up the ground. The warm air heated by the ground rising. The ground heating the air that is touching the ground. 6 / 20 What is convection? The movement of energy by waves. Any material that allows heat to move through it easily. The movement of heat from one solid to another. The way heat moves through liquids and gases. 7 / 20 How does a spark help start a fire? It provides the oxygen It provides the air It provides the fuel It provides the initial heat 8 / 20 Besides conduction, how else can you feel the fire's warmth even if you're not touching it? By smelling the smoke By seeing the flames By radiation 9 / 20 What is an insulator? Any material that allows heat (or electricity) to move through it easily. Any material that does not allow heat (or electricity) to pass through it easily. The energy of moving particles. The tool that is used to measure how hot or cold something is. 10 / 20 How is the sun similar to a fire in terms of heat? They both burn fuel. They both give off heat through radiation They both need oxygen to burn. 11 / 20 What is an conductor? The energy of moving particles. Any material that does not allow heat (or sound) to pass through it easily. The tool that is used to measure how hot or cold something is. Any material that allows heat (or electricity) to move through it easily. 12 / 20 Why is heat important for life on Earth? To melt snow and ice To help animals stay warm and plants grow To make campfires more enjoyable 13 / 20 What is a natural type of radiation? The heat waves from the sun heating up the ground The ground heating the air that is touching the ground. The sun directly touching the ground to transfer heat. The warm air heated by the ground rising 14 / 20 What is radiation? Any material that allows heat to move through it easily. The movement of energy by waves. The movement of heat from one solid to another. The way heat moves through liquids and gases. 15 / 20 What is a natural type of conduction? The ground heating the air that is touching the ground. The heat waves from the sun heating up the ground The warm air heated by the ground rising The sun directly touching the ground to transfer heat. 16 / 20 What is the narrator's main point in this story? To explain how fire and heat work together To show the importance of spending time with dad To teach how to build a campfire 17 / 20 How does convection help us feel warm around the campfire? The fire gets bigger when warm air rises. Warm air rises, carrying heat with it. Convection creates sparks for the fire. The logs burn faster because of hot air. 18 / 20 What is conduction? The way heat moves through liquids and gases. The movement of energy by waves. The movement of heat from one solid to another from direct contact. Any material that allows heat to move through it easily. 19 / 20 What three things does fire need to burn? Fuel, water and paper Paper, sticks and lighter Fuel, water and oxygen Fuel, oxygen and heat 20 / 20 How does heat travel from a mug of hot tea to your hands? By combustion By convection By radiation By conduction Your score is 0% Restart quiz Go to the Quizzes Page
