PPT-Temperature, Heat, and Thermal Energy

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 .

Email: 15818705@sun.ac.za. 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. 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. Chapter 6: Section 2. Before the video…. Get out a sheet of paper.. Write an example of each type of thermal energy transfer discussed in the video.. Bill Nye Clip. After the video. Draw a diagram of each type of thermal energy transfer that you listed from the video. Include the heat source, where it is going, and what it is heating up. . 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. Fins and Extended Surfaces. 1. Chapter 3c : One-dimensional, Steady state conduction (with thermal energy generation) (Section 3.5 – Textbook). 2. 3.1 Implications of energy generation. Involve a local source of thermal energy due to conversion from another form of energy in a conducting medium.. 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 . HEAT? TEMPERATURE?. How to measure temperature?. How to quantify temperature and heat?. How do heat transfer?. HEAT & TEMPERATURE. Temperature. is a quantitative measurement of . hotness/coldness.

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.
