Simple terms
|
Thermodynamic System (TS) any object or system of objects
|
|
Types of TS Isolated (no interaction with surroundings), Closed ( no mass exchange), open (mass exchange)
|
|
State Postulate Defines a number of properties required to fix a state
|
|
Intensive properties (mass ind.) if the property is the same
|
|
Extensive properties (mass dep.) if the property is doubled
|
|
|
Energys
|
macroscopic energys (Work) kinetic, potential
|
|
microscopic energys (Heat transfer) thermal, chemical, nuclear, etc
|

|
Closed U=Qnet-Wnet
|
|
Open U=Qnet-Wnet+ m(ein-eout)
|
|
adiabatic no heat transfer
|
|
isothermal T is constant
|
|
isobaric P is constant
|
|
isochoric V is constant
