PPT-TEMPERATURE AND HEAT TRANSFER OF THERMAL ENERGY

USING THERMAL ENERGY Thermal Energy Lesso n Objectives Explain the relationship between temperature and thermal energy Define heat and specific heat Thermal Energy Lesson Summary Heat is the transfer of thermal energy between objects that have different temperatures . Thermal Energy. Thermal energy results from the random movement of particles in a substance. Factors Affecting the thermal Energy of A . SUbstance. Factor. Factor Variation. Result. Number of Particles. Temperature. THE AVERAGE KINETIC ENERGY OF AN OBJECT.. Average motion energy. Thermal Energy. THE TOTAL KINETIC + POTENTIAL ENERGY IN AN OBJECT.. Energy of stored bonds + motion. Temperature Reference Points. Heat Transfer . is the transport of . thermal energy. due to a temperature difference across a . medium(s. ). mediums: gas, liquid, solid, liquid-gas, solid-gas, solid-liquid, solid-solid, etc.. Thermal Energy. Heat. is thermal energy that flows from something at a higher temperature to something at a lower temperature.. . 6.2. The Nature of Heat. Heat is a form of energy, so it is measured in . joules. . Transfer: Conductors . and Insulators. How is thermal energy transferred?. Why do materials expand and contract?. What materials are good conductors?. What materials are good insulators?. Key Vocabulary. . conduction. c. onvection. radiation. Energy can be transferred from one system to another (or from a system to its environment) in different ways: . Thermally. , when a warmer object is in contact with a cooler . Section 9.1: Temperature and Thermal Equilibrium. Defining Temperature. Temperature: a measure of the average kinetic energy of the particles in a substance. Adding or removing energy usually changes temperature. Heat. The transfer of thermal energy . Not a measure of energy but rather of energy transferred. . Measured in terms of joules or calories (cal). . Calories relate heat to changes in temperature. . Calorie is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. . Discovery Education Video:. This clip introduces heat, energy, and temperature. Some key terms and concepts are introduced. . Heat is a form of energy . that we can feel.. What is heat?. What is heat?. And Heat . Is Transferred. EQ: How can heat be transferred from one place to another?. Temperature. The weather report says that today’s high temperature will be 48 degrees and it will be cloudy. What should you wear?. Section 16.1 – Thermal Energy and Matter. In the 1700’s most . scientists. thought that . heat. was a . fluid. called . caloric. that flowed between objects.. Count Rumford. Rumford. studied the process of . Chapter. 18. Copyright © 2014 John Wiley & Sons, Inc. All rights reserved.. 18-. 1. . Temperature. 18.01 . Identify the lowest temperature as 0 on the Kelvin scale (absolute zero).. 18.02 . Explain the . Defining Temperature. Temperature: a measure of the average kinetic energy of the particles in a substance. Adding or removing energy usually changes temperature. Internal Energy: energies associated with atomic motion.
