Can CP be less than CV? This is a fundamental question in physics, chemistry, chemical engineering, and mechanical engineering. This question hangs in the minds of many students, instructors, and researchers. The first instinct is to answer “Yes, for water between 0 and 4 °C” if one knows that water expands as temperature decreases in this temperature range. The same question is asked in several Physical Chemistry and Physics textbooks. Students are supposed to answer that water contracts when heated at below 4 °C in an isobaric process. Because work is done to the contracting water, less …

Updates To A Sequence Of Thermodynamics Experiments For Mechanical Engineering Technology Students, Roger A. Beardsley
All Faculty Scholarship for the School of Graduate Studies and Research
This paper presents an outline of thermodynamics experiments and lab activities that accompany the introductory thermodynamics course for Mechanical Engineering Technology juniors at Central Washington University (CWU) in Ellensburg, Washington. It outlines and describes the current suite of thermodynamics lab activities, comparing the current suite of seven lab activities to a sequence outlined in an ASEE conference paper presented in 1995. Some lab activities in that paper have been replaced, while others have been updated. For example an experiment to measure the Joule-Thomson coefficient has been replaced with a First Law energy balance activity and the former First Law experiment …
