System and Extensive Intensive Properties
System
Isothermal
Boundary allows heat transfer from or to system
Temp of system constant
Adiabatic
Thermally insulated boundary
No heat transfer from or to system
Temp may change due to events within
Def
Region enclosed by a boundary, real or imaginary
Everything not in system = Surroundings
Types of Systems
Closed
Doesn't exchange mass
May exchange heat and wprl w/ surroindings
Open
Heat and mass can flow into or out of system
Isolated
does not exchange mass, heat, or work w/ surroundings
Extensive & Intensive Properties
Extensive Properties
Depend on extent or size of system
E.g.
Volume
Mass
Size
Weight
Intensive Properties
Don't depend on size of system
E.g.
Boiling Point
Color
Temp
Hardness
Properties
Density
mass/volume
Concentration
Number of Moles/Liters of Soln
Mole Fraction
Ratio # of moles of substance div by total # of moles in system
Moisture Content
Amount of H2O in sample
Wet Base
MCwb=mass of H2O/mass of moist sample
Dry Base
MCdb=mass of water/mass of dry solids
MCwb=MCdb/(MCdb+1)
MCdb=MCwb/(1-MCwb)
Temp
meausre of physiological response to hotnes or coldness
Celsius, Fahrenheit, Kelvin
Pressure
P=Force/Area
Normal force in a chamber
Atmospheric Pressure
Absolute Pressure
Pressure relative to absolute vacuum
Gauge Pressure
Difference b/ween absolute pressure and local atmospheric pressure
Fluid Pressure
Absolute Pressure= fluid density
gravity
height
Enthalpy
Internal energy and product of pressure and volume
Ideal Gas Law
Pressure = n(amount of gas (mol))
gas constant
Absolute Temp*Volume
