PPT-Heat (q) Heat : the transfer of energy between objects due to a temperature difference

Flows from highertemperature object to lowertemperature object System T 1 Surroundings T 2 Heat If T 1 gt T 2 q system exothermic System T 1 Surroundings T. Scales of Measurement. Celsius scale – based on where water freezes (0. . C) and where water boils (100. . C). Kelvin scale – based on the movement of particles. . Absolute Zero. At 0 K, all particle movement has ceased. Heat Energy. Heat energy is due to the movement of atoms or molecules.. As atoms move faster they create more energy = causing Heat!. Thermal Energy. Depends upon the mass, temperature and phase of an object.. 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. . 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. 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?. 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. . 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.
