PPT-Heat Energy and Temperature

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. Thermochemistry. Energy absorbed or released as heat in a chemical or physical change is measured in a . calorimeter. .. In some calorimeters, known quantities of reactants are submersed in water and combusted. The energy given off is noted by the temperature change in water.. 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. . 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. Pradeep Kumar Dadhich, PhD. Director| GUIDe - Energy and Resources. Deloitte Touche Tohmatsu India Private Limited. Three Essential Components are required for Waste Heat Recovery. Barriers and Research, Development, and Demonstration Needs Identified for Promoting Waste Heat Recovery Practices.

CH. 4(g). 2O. 2(g). CO. 2(g) . 2H. 2. 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. .
