Adiabatic Process

Compared to the other common thermodynamic processes (isochoric, isobaric, isothermal etc), what is unique about an adiabatic process?

Hint
Think in terms of volume, pressure, and temperature. What is changing? What is constant?
Hint 2
An isochoric process is constant volume, while an isobaric process is constant pressure, and an isothermal is constant temperature.
In an adiabatic process, heat transfer is zero. An isochoric process is constant volume, while an isobaric process is constant pressure, and an isothermal is constant temperature.
Heat transfer is zero.
