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