VIC101H1 Lecture : Lecture Jan. 5.docx - History of Time
Document Summary
Central idea; heat is a fluid substance called caloric. Central idea: heat is a form of energy. Central idea: heat consists of the motion of molecules or atoms, described statistically. Sadi carnot (reflections on the motive power of fire 1824) Purpose: analysis of production of work in idealized steam engines. Assumption: to generate power from heat you must have a cold body as well as a hot one. When air expands without doing work no heat is lost. Carnot and joule can be harmonized: heat and work are equivalent, in the carnot cycle part of the heat is converted to work and part is discharged at a lower temp. Each system tends toward the most probable molecular distribution. Each system tends toward the most probable thermo dynamic state.
