#### Course Description

Introduces physical properties of matter and energy, including properties of solids, liquids and gases. Presents applications of the basic equations of fluid mechanics, heat transfer, and the First Law of Thermodynamics, as well as application of these concepts to the human population's energy supply and demand. Prerequisites/concurrent: CMET 121, CMET 123. Audit available.#### Intended Outcomes for the course

Upon completion of the students should be able to:

- Identify physical properties of matter and energy including properties of solids, liquids, and gases.
- Utilize basic equations of fluid mechanics, heat transfer, and the First Law of Thermodynamics.
- Assess critically the energy supply and demand of the human population as well as that of individual countries.

#### Outcome Assessment Strategies

- Evaluation will include tests, homework and a final project.
- Specific details of the grading procedure will be given the first week of class.
- Lecture, homework, project and laboratory work will be coordinated.

#### Course Content (Themes, Concepts, Issues and Skills)

- A background in the topics covered in Global Energy Physics are needed in preparation for the subjects covered more in depth in Materials Technology, Fluid Mechanics, and Thermodynamics courses.
- Mechanical properties of gases, liquids, and solids must be understood in order to analyze and design machines, structures, and other engineering products.
