1.1 Thermodynamic System(열역학적계)
*Free body (diagram) in mechnics
= ∑ =0
(Newton`s 2nd law of motion)
*System in Thermodynamics
1)Closed System(밀폐계)
- fixed mass
- no mass transfer
- energy transfer
- control mass (검사질량, 고정질량)
thermodynamic universe = sys + surr
(열역학적 우주) (계) (계에 影響을 미칠수 있는 범위)
2)Isolated System(고립계)
- Special case of the closed System
- no mass transfer
- no energy transfer
- does not interact with surroundings
3)Open System
- energy and mass transfer
- fixed volume
- control volume(검사체적, 고정체적)
- flow system(유동계)
-choice of C.V depend on convinience of analtsis
1.2 property, state, process, and equilibruim
(물성치, 상태, 과정, 그리고 평형)
*Properties - macroscpic characteristics of system
(물성치) mass, volumme, energy, pressure, temp
(P, V, T, E, m)
- assigned @ given time
- Thermodyamics deals with quantities(상태) rather than propertie…(drop)
