Course Description

Introduces physical properties of matter and energy, includes properties of solids, liquids and gases. Presents applications of the basic equations of fluid mechanics, heat transfer, and the First Law of Thermodynamics. Prerequisites/concurrent: CMET 121, 123. Audit available.

Intended Outcomes for the course

The student will be able to:

  1. Recognize physical properties of matter and energy including properties of solids, liquids, and gases.
  2. Understand basic equations of fluid mechanics, heat transfer, and the First Law of Thermodynamics.

Outcome Assessment Strategies

  • Evaluation will include tests, homework and a final examination.
  • Specific details of the grading procedure will be given the first week of class.
  • Lecture, homework, and laboratory (usually problem solution on board) will be coordinated.
  •  Students must complete and/or participate in all three areas as indicated by the instructor.

Course Content (Themes, Concepts, Issues and Skills)

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



Instructional Goal:
