31critical mass — [n] crisis point critical point, critical stage, crossroads*, crunch time, do or die time*, high noon*, irreversible momentum, moment of truth, point of no return, sink or swim time*, the Rubicon, turning point; concept 674 …
32Critical variable — Critical variables are defined, for example in thermodynamics, in terms of the values of variables at the critical point. On a PV diagram, the critical point is an inflection point. Thus: For the van der Waals equation, the above yields …
33Critical threshold — Critical threshold, a notion derived from the percolation theory, refers to a threshold, that summons up to a critical mass. Under the threshold the phenomenon tends to abort, above the threshold, it tends to grow exponentially. In cases where… …
34critical constants — n. constant values related to the critical point of a substance, specif. the critical temperature, pressure, density, and volume * * * …
35critical constants — n. constant values related to the critical point of a substance, specif. the critical temperature, pressure, density, and volume …
36point of no return — point′ of no′ return′ n. 1) aer. the point in a flight at which an aircraft will lack sufficient fuel to return to its starting point 2) the critical point in an undertaking where one has committed oneself irrevocably to a course of action •… …

38Critical phenomena — In physics, critical phenomena is the collective name associated with the physics of critical points. Most of them stem from the divergence of the correlation length, but also the dynamics slows down. Critical phenomena include scaling relations… …
39Critical temperature — The critical temperature, Tc, of a material is the temperature above which distinct liquid and gas phases do not exist. As the critical temperature is approached, the properties of the gas and liquid phases become the same resulting in only one… …
40Critical line (thermodynamics) — In thermodynamics, a critical line is the higher dimensional equivalent of a critical point [1]. It is the locus of contiguous critical points in a phase diagram. These lines cannot occur for a single substance due to the phase rule, but they can …
