Students learn the fundamental concepts of heat transfer and heat of reaction. This includes concepts such as physical chemistry, an equation for heat transfer, and a basic understanding of energy and heat transfer.

Among many other things that we use every day, engineers design industrial plants and processes that make usable products from chemicals, such as food products, medicines, materials, and fuels. To safely and efficiently apply and control these processes, engineers must know how much heat will be generated in a given reaction. If too much heat is generated, proteins denature, products burn or decompose, or a reactor might explode. If too little heat is generated, the chemicals do not react, enough energy might not be created, and the wrong products are produced. In addition to reaction temperatures, an engineer must also have an understanding of the specific heat capacity of various substances. Heat capacity refers to how much energy is required to change the temperature of a substance by one unit temperature. Engineers need to understand heat capacity for a variety of reasons, such as determining how hot metal parts in an engine will get or how much energy must be added to a chemical reactor to raise or lower the contents to the desired temperature. Describe that specific heat capacity is the amount of energy an object can absorb before changing in temperature by one unit temperature.Explain how heat capacity, heat of reaction and heat transfer can be applied in engineering to understand and control chemical processes and physical systems.Identify exothermic reactions as heat generating, and endothermic reactions as heat consuming.20TeachEngineering.orgJames PragerMegan SchroederMalinda ZarskeJanet Yowellhttp://www.nist.gov/public_affairs/techbeat/tb2008_0123.htm http://www1.eere.energy.gov/industry/petroleum_refining/profile.htmlS11417DDInternational_Technology_Education_Association-ITEA_STL_StandardsTechnologyJ. Energy cannot be created nor destroyed; however, it can be converted from one form to another. 912S11417DEInternational_Technology_Education_Association-ITEA_STL_StandardsTechnologyK. Energy can be grouped into major forms: thermal, radiant, electrical, mechanical, chemical, nuclear, and others. 912S11424CCColoradoScienced.
