Page 123 1 cold, WARMER, melt 2 A man and woman are warming their cold hands by a fire because their hands are receiving heat energy via convection currents from the transfer of radiant energy of the fire 3 one who facilitates the organization and performance of music 4 a form of heat energy transfer that occurs through direct contact and molecules that are colder receiving heat energy from molecules that are warmer Page124 5 Thermal energy is the energy of all particles of the substance so the 2 factors influencing Thermal Energy are the amount of the substance and the average amount of kinetic energy present in the substance (Temperature) Page 125 6 pot of soup, large baloon, tiger
Page 126 7 metal rod fire hat snow man ice cube glass warm water Page 127 8 The girls are warmer than the cold air around them so the heat energy flows from the girls to the air around them. 9 Energy will be transferred from the WARMER object to the COLDER object until both objects are the same temperature FIGURE IT OUT IN YOUR NOTEBOOK: TITLE IT HOW MANY CALORIES 11/25/14 A burned a banana in a calorimeter produced 501,600 Joules. How much energy in Calories did the banana contain
Page 128 10 To touch hot objects: oven mitt, pot holder, towel To touch cold objects: mittens, gloves, scrapper, a warmer object (warm water on frosted windows) All of these are not metals so they fail to conduct heat. 11 add or subtract heat energy will create a phase/state change. 12 flannel shirt insulator, Iron Skillet conductor, Copper Pipe conductor, oven mitt insulator VOCABULARY SECTIO OF NOTEBOOK: Calorie – amount of energy needed to raise the temperature of 1 g of water 1 degree Celsius Specific Heat-the number of calories needed to raise the temperature of 1 g of any substance 1 degree Celsius Page 129-130 13 Water moves in irregular circular patterns because of convection currents transferring heat energy… Examples of electromagnitic waves include visible light, microwave, infrared and radiant energy from the sun…all objects emit radiant energy, even you. 14 radiation, hot burner warming a cold pot, convection
Page 131 17 The sun is the source of radiation for the solar cooker used to cook food. Page 132 18 Two object at the same Temperature, then the one with more particles will have higher thermal energy. 19 not to cold 20 Adding heat causes bonds to break. 21Conduction requires direct contact between objects to transfer heat. 22 The sun’s energy uses radiation to travel to Earth. 23 Standing in the shade avoids radiation from the sun by blocking the electromagnetic waves.
