Reversible adiabatic processes are isentropic but this is not really reversible, if the external pressure were zero .-- talk ) 04 : 04, 12 October 2008 ( UTC)

And a final note : many physicists, including myself, normally use the words " adiabatic process " only when they are talking about reversible adiabatic ( = isentropic ) process.
43.
Paraelectricity has been explored as a possible refrigeration mechanism; polarizing a paraelectric by applying an electric field under adiabatic process conditions raises the temperature, while removing the field lowers the temperature.

adiabatic process : If the cylinder is a perfect insulator, the initial top-left state cannot be reached anymore after it is changed to the one on the top-right.
45.
Potential temperature is conserved for all dry adiabatic processes, and as such is an important quantity in the planetary boundary layer ( which is often very close to being dry adiabatic ).
46.
The parcel of air can only slowly dissipate the energy by conduction or radiation ( heat ), and to a first approximation it can be considered adiabatically isolated and the process an adiabatic process.
47.
The adiabatic process has been important for thermodynamics since its early days . It was important in the work of Joule, because it provided a way of nearly directly relating quantities of heat and work.
48.
So, for an adiabatic process, a particle starting from nth eigenstate also remains in that nth eigenstate like it does for the time-independent processes, only picking up a couple of phase factors.
49.
Convection is the dominant mode of energy transport when the temperature gradient is steep enough so that a given parcel of gas within the star will continue to rise if it rises slightly via an adiabatic process.
50.
The most common daily pattern follows an adiabatic process, with a calm, clear morning, followed by a breeze blowing in from higher pressures over the sea, culminating in a cloudy and drizzly afternoon.
