Document Summary
Chapter 3: thermodynamic principles: a review: thermodynamics(therme: heat, dynamis:power): description of the relationships amoung different forms of energy and how energy affects matter on the macroscopic rather than the molecular level. >deals with matter large enough for their average properties. >ex: temperature and pressure: thermodynamics can determine if a physical process is possible. Conserved: a system is the part of the universe. >reaction vessel or an organism: the rest of the world is surroundings, a system is either open, closed or isolated. State functions are independent of the path a system follows: experiments have shown that the energy of a system depends on its properties or state, not how it got to that sate. >ex: state of a gas system is described by its pressure and temperature-energy of this gas sample is a function of state functions (quantities that depend only on the state of the system)
