Thermodynamics
Cards in this deck (15)
- 1Define: SystemThe part of the Universe we choose to study
- 2Define: SurroundingsThe area around the system
- 3Define: BoundaryThe border between the Universe and its surroundings
- 4What does an Open system imply?That Mass and Energy can be transferred between the System and its Surroundings
- 5What does a Closed system imply?That Energy, but not Mass, can be transferred between system and surroundings
- 6What does an Isolated system imply?That neither Mass nor Energy can be transferred between system and surroundings.
- 7What knowledge is required to describe a system?Macroscopic properties; knowledge of equilibrium state; knowledge of homogenous or heterogenous state; knowledge of # of components
- 8What are Extensive properties?Properties that are dependent on the size of the system
- 9What are intensive properties?Properties which are independent of system size.
- 10How is the state of a system at equilibrium defined?By the collection of all macroscopic properties, that are described by state variables
- 11What is required to obtain the macroscopic properties of a one-component system?"n" and 2 additional variables (where "n" is moles)
- 12What is the 0th Law of Thermodynamics?Three systems have a syllogistic (if A=B and B=C then A=C)description of thermal equilibrium
- 13Operational Definition of TemperatureNeed: substance, property that depends on t, reference points, interpolation scheme between reference points
- 14The Ideal Gas LawpV = nRT or pV=RT
- 15WorkWork = Applied Force * Distance
