## Engineering Performance Matrix

Thermodynamics is the science of transferring energy from one place or form into another place or form which includes the study of heat and temperature and the relation of these factors to work, energy, and power. This concept is important to Engineering Literacy, as it is the basis on which engineering professionals calculate and predict how forms of energy are converted into other forms in order to create, improve, and create technological products and systems such as power plants, air-conditioning/heating units, and automobile engines.

## Performance Goal for High School Learners

I, when appropriate, draw upon the knowledge of Thermodynamics content, such as (a) the Laws of Thermodynamics, (b) equilibrium, (c) gas properties, (d) power cycles and efficiency, and (e) heat exchangers, to analyze the forces within an energy system to solve problems in a manner that is analytical, predictive, repeatable, and practical.
