Lecture 3: FIRST LAW OF THERMODYNAMICS
... The rate of heat loss of a body is proportional to the temperature difference between the body and its surroundings. Lavoisier: 1790 Heat consists of a self-repellent fluid, caloric, that flows from hotter bodies to colder bodies. Joule and Thomson: 1851 Heat is not a substance, but a dynamical form ...
