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.. 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).. How do we measure Temperature?. Thermal expansion . – The fluid in a thermometer’s bulb heats up and expands, increasing the volume until it flows up the tube of the thermometer.. Color change. – Some materials change color based on their temperature. Examples are forehead thermometers and mood rings.. 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?. 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. . Heat. Heat. is energy that flows from a higher-temperature object to a lower-temperature object because of the difference in temperatures.. SI Unit of Heat:. joule (J).. SI unit for heat is the joule, J. By . Dr. Hussein . ALNaji. Hyperthermia is the elevation of core body temperature caused by excessive heat production or absorption, or to deficient heat loss, when the causes of these abnormalities are purely physical.. Understand the reactions of carbonyl compounds with:. HCN, in the presence of KCN, as a nucleophilic addition reaction, using curly arrows, relevant lone pairs, dipoles and evidence of optical activity to show mechanism. Clausius. – . Clapeyron. equation, Temperature dependence of entropy, Statistical interpretation of entropy, Consequences of third law, Nernst heat theorem, Equilibrium constant, Van-Hoff equation, Concept of fugacity, activity and mole fraction.
