Happy New Week. The week's topics: UPDATED!! First Law of Thermodynamics: - the first law as it relates to the universe; - revision of heat, work, the thermodynamic potentials (U, H, A, G); and - the 1st Law and its application to Open Systems "Thermodynamics is a branch of physics which deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. Small scale gas interactions are described by the kinetic theory of gases. There are three principal laws of thermodynamics which lead to the definition of thermodynamic properties which help us to understand and predict the operation of a physical system." (NASA). “The first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic processes.” (All energy in the universe is accounted for). “The laws of thermodynamics are special laws upon which the other [natural] laws depend”...
