adiabatically
Adverb
Meaning
adiabatically (not comparable)
(sciences) In an adiabatic way.
Examples
For instance, when scientists at the NIST achieved a record-setting cold temperature of 700 nK (billionths of a kelvin) in 1994, they used optical lattice laser equipment to adiabatically cool caesium atoms.
In classical thermodynamics, such a rapid change would still be called adiabatic because the system is adiabatically isolated, and there is no transfer of energy as heat.
In this sense, a rapid compression of a gas is sometimes approximately or loosely said to be adiabatic, though often far from isentropic, even when the gas is not adiabatically isolated by a definite wall.
It is sometimes possible to change the state of a system diabatically (as opposed to adiabatically ) in such a way that it can be brought past a phase transition point without undergoing a phase transition.
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.
The transfer of energy as work into an adiabatically isolated system can be imagined as being of two idealized extreme kinds.
