"… there need be no entropy generated in adiabatic processes – which occur frequently in living systems …".
Air must be compressed, then cooled, and then allow to expand, this is called adiabatic cooling.
Cv, also sometimes called the adiabatic index or the heat capacity ratio or the isentropic expansion factor
The result is what meteorologists call adiabatic cooling - the temperature plunges to below - 30C, causing the water vapour in the gas to condense.
The adiabatic combustion temperature (also known as the adiabatic flame temperature) increases for higher heating values and inlet air and fuel temperatures and for stoichiometric air ratios approaching one.
New paradigms of quantum algorithms have appeared, such as adiabatic algorithms, measurement-based algorithms, and topological-quantum-field-theory-based algorithms, as well as new physical models for realizing a large scale quantum computer with cold ion traps, quantum optics (using photons and optical cavity), condensed matter systems and solid state physics (meanwhile, the first NMR model had turned out to be a dead-end with respect to scaling; see DiVicenzo 2000).
This is called the adiabatic lapse rate, and it’s a simple consequence of Boyle’s Law.
I'll refine response that a wee bit. "adiabatic" means without change in * heat* energy.
Gavin corrected him: Since 'adiabatic' means without input of energy it seems a little unlikely that it is a source of Venusian heating. - gavin
Giauque, who extended the temperature range experimentally accessible by introducing the method of adiabatic demagnetization in 1933.
