Ch 1
Property: Any characteristic of a system.
volume (V)
temperature (T)
Tk=Tc+273K
mass (m)
pressure (P)
Specific volume =V/m
System : The region chosen for study :
Open system : energy cross, mass cross , At least one is imaginare.
Control surface : energy and mass cannot cross
Cosed system : energe cross ,mass cannot cross ,Boundary are real
Boundary:surface bel system and surroundings
real Boundary
imaginary Boundary
Thermodynamics: Science of energy
الهدف منه : heat يتبادل مع Work
Gage pressure
Pgauge+Patm=Ptotal=Preal=Pabs
Vacuum pressure
Patm-Pvac=Pabs
Energy :ability to do work or change
Surroundings :region outside the system
The first law of Thermodynamics: An expression of the conservation of the conservation.
