	Adiabatic process - Wikipedia, the free encyclopedia
		Another example is the adiabatic flame temperature, which is the temperature that would be achieved by a flame in the absence of heat loss to the surroundings.
		Since temperature is thermodynamically conjugate to entropy, the isothermal process is conjugate to the adiabatic process for reversible transformations.
		Adiabatic heating and cooling are processes that commonly occur due to a change in the pressure of a gas.

	Cyclic process - Wikipedia, the free encyclopedia
		A cyclic process is a thermodynamic process which begins from and finishes at the same thermostatic state.
		Equation (1) makes a cyclic process similar to an isothermal process: even though the internal energy changes during the course of the cyclic process, when the cyclic process finishes the system's energy is the same as the energy it had when the process began.
		The adiabatic processes are impermeable to heat: heat flows into the loop through the left pressurizing process and some of it flows back out through the right depressurizing process, and the heat which remains does the work.

		Adiabatic processes are processes in which no heat is gained or lost in the working fluid.
		In quantum mechanics, an adiabatic change is a sufficiently slow change in the Hamiltonian which would result only in a change of eigenvalues, not eigenstates.
		If, in such a process, there is a qualitative change in the properties of the ground state (for example the spin), the change is called a quantum phase transition.

	Adiabatic lapse rate - Wikipedia, the free encyclopedia
		The adiabatic lapse rate is the rate of temperature change that occurs in an atmosphere as a function of elevation, assuming that air behaves adiabatically (thermally insulated).
		The dry adiabatic lapse rate (DALR) is the rate at which a rising parcel of unsaturated air, such as a thermal, will lose temperature.
		They are used to determine if the parcel of rising air will rise high enough for its water to condense to form clouds, and, having formed clouds, whether the air will continue to rise and form bigger shower clouds, and whether these clouds will get even bigger and form cumulo-nimbus clouds (thunder clouds).

	Adiabatic Processes
		This is called adiabatic heating and cooling, and the term adiabatic implies a change in temperature of the parcel of air without gain or loss of heat from outside the air parcel.
		Adiabatic processes are very important in the atmosphere, and adiabatic cooling of rising air is the dominant cause of cloud formation.
		This is called the Saturated adiabatic lapse rate (or the wet adiabatic lapse rate, or the moist adiabatic lapse rate, depending on the textbook you are using).

		An adiabatic process is a process in which no energy is added to or taken away from the system (the "system" usually is a parcel of air).
		A saturated adiabatic process (sometimes called a moist adiabatic process or pseudo adiabatic processes) is an adiabatic process in which the system becomes saturated and latent heat is released or absorbed by the water molecules, thus offsetting the dry adiabatic temperature changes.
		The lower value of the moist adiabatic rate, compared to the dry adiabatic rate, is due to the release of latent heat during the condensation process.

		Admittedly the process is not entirely adiabatic, but it only takes a few seconds to release the pressure in the bottle and the plastic is not very conductive nor is it a large heat sink, it should be nearly adiabatic.
		If the bottle were well insulated and the expansion quick enough, an adiabatic process could be safely assumed, not so for reversibility, thus it wouldn't be isentropic, and the thermophysical properties of the leaving gas would differ from those of the gas left behind in the bottle.

	Stability & Cloud Development
		An adiabatic process is one where no heat is exchanged between an air parcel and the surrounding air.
		When we talk about an adiabatic process in the current context we are talking about a rising (or sinking) parcel of air that is not exchanging any heat with its surroundings.
		Since the moist adiabatic rate must be less than the environmental lapse rate for stable conditions to exist, a moderate to small environmental lapse rate enhances stability in the atmosphere.

		Introduction In applied physics, an adiabatic process is defined as any process that is asymptotically isentropic (thermodynamically reversible), that is, whose total entropy generated tends towards zero in some appropriate limit (typically, of low speed and/or improved isolation of the system).
		The existence of adiabatic processes is an everyday fact, exemplified by the ballistic motion of a projectile in a near-vacuum environment (e.g.
		The degree of adiabaticity of any process can be defined as equal to its quality factor Q, in the sense used in electrical and mechanical engineering, i.e., the ratio between the amount of free energy involved in carrying out the process, and the amount of this energy that gets dissipated to heat.
