The stable phases shown in the phase diagram (formed at atmospheric pressure under an atmosphere of normal humidity) are:

I had caught the later, stable phase.

Although the band had gone through significant personnel changes in previous years, the band would enter its most stable phase with this line up.

The classic example is diamond, which is unstable with respect to graphite, the most stable phase of carbon at 1 atmosphere and 298.15 Kelvins.

It is important to recognize that all described exercise programs were conducted by physicians or physiotherapists during the stable phase of the disease (except Painelli).

The star then contracts, leaving the red giant phase and continuing its evolution into a stable helium-burning phase.

How long did you hold the stable phase, and what was the lowest body temperature?

Once the creature had been forced into a stable and visible phase, its progress had slowed a bit.

The stable phase under normal conditions is orthorhombic with 8 atoms in the conventional unit cell.

Many stable and metastable phases are found as function of temperature and pressure.
