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)

Describes experiments designed to investigate the cooling rate of microwave-boiled water as compared to that of stove-boiled water. Concludes that within experimental limits, microwave-boiled water and stove-boiled water cool at the same rate. (JRH)

Provides an alternative derivation of the Boltzmann distribution based on the minimization of the Helmholtz free energy. (CS)

Provides information concerning the Boltzmann distribution mentioning partition functions, spectroscopy, basic mathematics, and its relation to temperature distribution. (CS)

Presents a step-by-step approach to be used in solving different forms of physics problems, starting from familiar grounds and finding well known results on the way. Uses the rate of heat flow and the resulting changes of temperature with time of a copper block as an example. (GA)

Provides a rigorous but straightforward thermodynamic treatment of the temperature dependence of the solubility of solids in liquids that is suitable for presentation to undergraduates, suggesting how to approach the qualitative aspects of the subject for freshmen. Considers unsolvated/solvated solutes and Le Chatelier's principle. (JN)

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)

Presents activities that integrate physics, earth science, and health. Students explore their own sensible temperature focusing on the physical processes of heat transfer. (DDR)

Describes a method to demonstrate induction heating by placing an ordinary mercury thermometer in a high frequency magnetic field and observing the temperature rise. Also describes an ice calorimeter for measuring the mechanical equivalent of heat. (SK)

Reviews some important properties of the bimolecular reaction between the hydroxyl radical and carbon monoxide. Investigates the kinetics of the reaction, the temperature and pressure dependence of the rate constant, the state-to-state dynamics of the reaction, and the reverse reaction. (MVL)

Suggests an apparatus to improve the measurement of the mechanical equivalent of heat. Describes the materials needed to construct the apparatus; the methodology of an experiment to measure the heat gained by lead shot falling through a distance of 100 meters; and the calculations made to register that gain. (MDH)

Describes an apparatus capable of measuring absolute temperatures of a tungsten filament bulb up to normal running temperature and measuring Botzmann's constant to an accuracy of a few percent. Shows that electrical noise techniques are convenient to demonstrate how the concept of temperature is related to the micro- and macroscopic world. (CW)

Describes phase transition in solids and shows how soap films can be used to demonstrate this phenomenon. (Author/SK)
