PPT-Thermochemical

Calculations CA Standards Students know energy is released when a material condenses or freezes and is absorbed when a material evaporates or melts Students know how to solve problems involving heat flow and temperature changes using known values of specific heat and latent heat of phase change. 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.. Quick Review of Concepts. We have been introduced to heat producing (. exothermic. ) reactions and heat using (. endothermic. ) reactions. Heat is a measure of the transfer of . energy. from a system to the surroundings and from the surroundings to a system. Thermochemical Recuperation for High Temperature Furnaces Waste Heat Recovery Technology for Process Heating in the Steel Industry The potential steel market for the technology could be 75% of the Feeling hot, hot, . hot. Thermochemistry. Thermochemistry. – concerned with the changes that occur during a. reaction.. Heat ( ) - that transfers from one object to another because of a. conversion technology . – charcoal production. Introduction . What is charcoal?. Transformations during pyrolysis. Charcoal yields. The charcoal making process. The Drying Phase. The Pyrolysis Phase. Using the grid to solve for desired . quanties. . Recap . An . exothermic. change is a reaction that releases energy: energy can be thought of as a product . An . endothermic. change is one in which the energy must be added for the reaction to occur: energy can be thought of as a reactant . Bradley Welch and Richard Dawes. Introduction. What is the .
