PPT-Chapter 1: Temperature and Heat

HEAT TEMPERATURE How to measure temperature How to quantify temperature and heat How do heat transfer HEAT amp TEMPERATURE Temperature is a quantitative measurement of hotnesscoldness. Temperature. Most materials expand when heated. Liquid thermometers based on mercury or alcohol expansion are common. Temperature is related to the random motion of atoms and molecules in a substance. . 3.1 …………. Introduction. 3.2 …………. Biot and Fourier Number. 3.3 …………. . Lumped heat capacity analysis. 3.4 …………. Time constant and response of a thermocouple. 3.5 …………. Transient. On the front counter there is a perpetually thirsty bird. Do NOT touch him.. Write down all your . observations. of the motion. Do not try to explain why it’s happening—just look at WHAT is happening. . Introduction to Heat. Heat is a form of energy.. A large amount of energy ends up as heat.. Example: in a car some of the chemical energy stored in petrol is turned into heat energy. . Heat can have a significant effect on solids, liquids and gases (such as expansion).. 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. 2.1. Temperature and the . Zeroth. Law of Thermodynamics. 2.2. Thermal Expansion. 2.3. Heat and the Absorption of Heat by Solids and Liquids. 2.4. Work and Heat in Thermodynamic Processes. 2.5. The First Law of Thermodynamics and Some Special Cases. 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 . Calculations.
