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