- System
- Whatever we want to study
- Surroundings
- Everything outside the system
- Boundary
- what distinguishes the surroundins
- Closed system
- has no transfer of mass
- Isolated System
- Closed system that does not interact with its surrondings
- Property
- a characteristic such as mass, volume, energy, pressure, and temperature
- State
- refers to the condition of the system as described by its properties.
- Process
- When any of the properties of a system undergo a change
- Steady State
- none of the properties change with time
- Thermodynamic process
- a sequence of processes that begins and ends at the same state.
- Phase
- matter that is homogeneous throughout in both chemical compositon and physical structure
- Pure substance
- uniform and invarible in chemical compostion
- thermometric property
- measurable property changes as its temperature changes
- triple point of water
- the state of equilibrium b/w stream, ice, and water
- w>0
- word done by the system
- w<0
- work done on the system
- work is not a property
- True
- Power
- the rate of energy transfered by work
- quasiequilibrium process
- one in which all states trough which the system passes may be considered equilibrium states.
- convection
- energy transfer trough gas or liquid
- transient
- state changes with time
