During an introductory course in thermodynamics, undergraduate engineering students are reintroduced to scientific fundamentals that include conservation of energy (also known as the first law of thermodynamics) and conservation of mass. To help support these concepts, a simple lab experiment was created based on work from Robert Edwards (Pennsylvania State University) using a hairdryer along with basic measuring equipment. The amount of energy being drawn to run the hairdryer should equal the amount of heat energy leaving the open system. A variety of data is collected and applied to familiar equations to reduce the amount of error to be within 10%. Alterations to the published experiment were made based on the author’s observations and available equipment.
