In Instruction About Heat Energy And Temperature

ABSTRACT Pedagogical content knowledge, the content-specific knowledge which embodies the aspects of content most germane to its teachability and which is most likely to distinguish the understanding of the content specialist from the pedagogue. has been widely regarded as important for effective teaching of complex subject matter such as science. This paper focuses on one aspect of pedagogical...

Saturn's atmospheric temperature structure and heat budget

The effective temperature of Saturn from 30øS to 10øN is 96.5 + 2.5 K. This value is 1.9 K higher than our preliminary estimate (Ingersoll et al., 1980). The atmospheric mole fraction of H2 relative to H2 + He is 90 + 3%. This value is derived by comparing infrared and radio occultation data (Kliore et al., this issue) for the same latitude. The high value of the effective temperature suggests ...

Quantum heat engines and nonequilibrium temperature.

A pair of two-level systems initially prepared in different thermal states and coupled to an external reversible work source do not in general reach a common temperature at the end of a unitary work extraction process. We define an effective temperature for the final nonequilibrium but passive state of the bipartite quantum system and analyze its properties.

Temperature Regulation, Heat Balance and Climatic Stress

Th is paper discusses human thermoregulation and how this relates to health problems during exposure to climatic stress. Th e heat exchange of the body with the environment is described in terms of the heat balance equation which determines whether the body heats up, remains at stable temperature, or cools. Inside the body the thermoregulatory control aims at creating the right conditions of he...
