What does an Open system imply?	That Mass and Energy can be transferred between the System and its Surroundings
What does a Closed system imply?	That Energy, but not Mass, can be transferred between system and surroundings
What does an Isolated system imply?	That neither Mass nor Energy can be transferred between system and surroundings.
What knowledge is required to describe a system?	Macroscopic properties; knowledge of equilibrium state; knowledge of homogenous or heterogenous state; knowledge of # of components
What are Extensive properties?	Properties that are dependent on the size of the system
What are intensive properties?	Properties which are independent of system size.
How is the state of a system at equilibrium defined?	By the collection of all macroscopic properties, that are described by state variables
What is required to obtain the macroscopic properties of a one-component system?	"n" and 2 additional variables (where "n" is moles)
What is the 0th Law of Thermodynamics?	Three systems have a syllogistic (if A=B and B=C then A=C)description of thermal equilibrium
