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