Presents a discussion and examples of the two categories into which solar homes have been classified. Classifications are based upon the method by which the sunlight is put to use: energy conversion, utilizing photoelectric cells; and direct heating, where sunlight heats water which then heats the home. Diagrams are presented. (Author/EB)

An experiment was performed that allowed measurements of both axial mass and heat transport of He-II (the superfluid phase of helium 4) in a long tube. The apparatus allowed the pressure difference and the temperature difference across the flow tube to each be independently adjusted, and the resulting steady-state values of net fluid velocity and…

Studies the practicality of water-filled flat-plate solar collectors. An estimate of solar energy gathering abilities and applications in heating of homes are considered. (CP)

Terraset is a hill with a school inside, located in Reston, Virginia. A solar collector, heat reclamation system, and the earth cover save energy. (Author/MLF)

Describes the design of a low-cost electronic circuit to serve as a differential thermostat, to control the operation of a solar heating system. It uses inexpensive diodes for sensoring temperature, and a mechanical relay for a switch. (GA)

Discusses the role of phonon quasi-particles in a wide range of phenomena from simple thermal properties to super conductivity and other electric and magnetic phase transitions. (MLH)

Argues that previous definitions of work and heat are inappropriate. Presents new definitions that are formulated using experimental quantities, claiming that they apply equally well to reversible and irreversible processes. Indicates some of the problems with earlier definitions and applies the new definitions to the First Law of thermodynamics.…

This textbook is a course on properties of heat. The first seven lectures of the course deal with "thermometric heat" and its generation and consumption in mechanical processes; the determination of the mechanical equivalent of heat; the conception of heat as molecular motion; the application of this conception to the solid, liquid, and…

Describes laboratory experiments designed to demonstrate (1) the properties of cholesteric liquid crystals, (2) thermal mapping, (3) thermal diffusivity, (4) adiabatic expansion of rubber, and (5) measurement of radiated energy by a point source. Contains all of the information on materials and apparatus needed to perform the experiments.…
