Physical dependence, whether to an opioid or to an immune-suppressing drug like prednisone, involves reversible changes in body tissues.
12.
One may imagine reversible changes, such that there is at each instant negligible departure from thermodynamic equilibrium within the system.
13.
We now consider an infinitesimal reversible change in the temperature and in the external parameters on which the energy levels depend.
14.
Their ability to undergo huge though reversible changes in volume allows new systems to be created that can envelop and release materials.
15.
However, classical thermodynamics is mostly concerned with systems in reversible changes and not what actually does happen, or how fast, away from equilibrium.
16.
This relation applies to a reversible change, or to a change in a closed system of uniform temperature and pressure at constant composition.
17.
However, this is a reversible change, so probably not what the OP meant . talk ) 19 : 53, 28 September 2014 ( UTC)

Somehow, someone has found a way to create a neuropharm that causes fast-acting, non-reversible changes in brain chemistry, in this case inducing fear of novelty.
19.
This combination of inflammation and ischemia may produce reversible changes such as demyelination alone, or more permanent damage axonal ( necrosis ), or a combination.
20.
Even though the light-induced activation step is usually irreversible, reversible changes can be induced in a number of photoswitches, which will not be discussed in detail here.
