 | The condition of compressed air is determined by the 3
measures of thermal state:
T = Temperature
V = Volume
p = Pressure
|
constant volume
isochore compression | This means:
Volume constant (isochor)
Pressure and temperature variable
When the temperature is increased and the volume remains
constant, the pressure rises.

|
constant temperature
isotherm compression | Temperature constant (isotherm)
Pressure and volume variable
When the volume is reduced and the temperature remains
constant, the pressure rises.
|
constant pressure
isobar compression | Pressure constant (isobar)
Volume and temperature variable
When the temperature is increased and the pressure
remains constant, the volume increases.
