### Heat Transfer Answer KeyPlay This Game

 All things Heat #1 the energy of motion What is kinetic energy? #2 the transfer of thermal energy from a warmer to cooler object What is heat? #3 The AVERAGE kinetic energy that the particles in a substance has What is temperature? #4 The TOTAL kinetic energy that the particles in a substance has What is thermal energy? #5 faster moving particles will have _______ kinetic energy and therefore a _______ temperature than slower moving particles more; higher
 Methods of Heat Transfer #1 The transfer of heat by direct contact between particles What is conduction? #2 The transfer of heat through empty space by electromagnetic waves What is radiation? #3 The transfer of heat by warmer fluids rising and cooler fluids sinking What is convection? #4 Explain how conduction works when substances come in contact with each other, the particles bump into each other giving away some thermal energy #5 Explain how convection works fluids close to the heat source warm up, the particles spread out, becoming less dense, fluid rises; cooler fluid is less dense so it sinks
 Characteristics of Heat #1 Heat always moves from _________ to __________ warmer to cooler #2 T or F: The temperature of a substance depends on how much of the substance you have False #3 T or F: The thermal energy of a substance depends on how much of the substance you have True #4 In which phases of matter do the particles have kinetic energy? All phases #5 What are the 3 scales for measuring temperature? Fahrenheit, Celsius, and Kelvin
 Materials for Heat Transfer #1 materials that transfer thermal energy well What are conductors? #2 materials that do NOT transfer thermal energy well What are insulators? #3 Give two examples of conductors glass, metal, tile #4 Give three examples of insulators various answers #5 What are insulators used for? use to prevent or slow down the transfer of thermal energy
 Examples of Heat Transfer #1 you burn your hand when you touch the metal end of a curling iron conduction #2 a heater located in the deep ened warms an entire swimming pool convection #3 the sunlight shines directly on you through the window making you feel hot radiation #4 Your feet feel cold as you walk onto the tile floor in your bathroom conduction #5 when you sit facing a campfire, your face feels warm but your back feels cold radiation
 Final Question Which will have more thermal energy: an ice sculpture or a burning match? Explain ice sculpture; even though it has a lower temperature, it has A LOT more particles than a match has. and thermal energy is TOTAL kinetice energy
