Discusses the definition of temperature and the concept of order in non-mathematical terms. Describes the cooling techniques necessary in low temperature physics research, including magnetic cooling, the use of the Pomeranchuk Effect, and dilution refrigeration. Outlines the types of phenomena observed in matter within various temperature ranges…

Demonstrates misconceptions of the meaning of temperature based on classical kinetic energy. Discusses some misconceptions about negative temperatures and the effect of compression. (YP)

Discusses interesting aspects of the Carnot cycle and other thermodynamic cycles that are generally not dealt with in elementary physics texts. Presents examples that challenge the student to think about the extraction of net work from a cycle. (JRH)

Presents a range of experiments in heat conduction suitable for upper-level undergraduate laboratories that make use of heat sensitive liquid crystal film to measure temperature contours. Includes experiments mathematically described by Laplace's equation, experiments theoretically described by Poisson's equation, and experiments that involve…

Identifies practical ways to introduce students to thermodynamic concepts, such as heat and mechanical energy. Introduces three different energy transformations that everyone should be able to envisage. (SOE)

Emphasizes firewalking as a good illustration of basic concepts in thermodynamics. Describes the basic principles of firewalking and other factors including the cooling of the surface embers, moisture of the feet, thick skin on the feet, tolerance for pain, and other uncontrolled factors. (YP)

Adolescents (n=151-158), adults (n=18), and scientists (n=5) were involved in two studies conducted to identify concepts of heat energy and temperature held by each of the participants and investigate the impact of a middle school science curriculum designed to help students understand everyday thermal events. Results indicate that each group had…

Discusses the history of the development of Newton's Law of Cooling. Describes an experiment conducted in the kitchen that is designed to test the rate of cooling of a hot block of iron. Finds that Newton's law does not represent very well the mechanism of heat loss. (Contains over 10 references.) (WRM)

Traces the history and development of temperature scales which began with the 17th-century invention of the liquid-in-glass thermometer. Focuses on the work of Olaf Romer, Daniel Fahrenheit, Rene-Antoine de Reamur, Anders Celsius, and William Thomson (Lord Kelvin). Includes experimental work and consideration of high/low fixed points on the…
