For example, ice is the solid state of water, but there are multiple phases of ice with different crystal structures , which are formed at different pressures and temperatures.
Furthermore, the hair cells, the sound receptors found within the cochlea, can be permanently damaged and can result in a hearing loss of a mild to profound degree. [4] Additionally, the intensity of the pressure changes from the blast can cause injury to the blood vessels and neural pathways within the auditory system .
Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate
The psychological elements are as important as the financial ones.
The boost phase is the portion of the flight of a ballistic missile or space vehicle during which the booster and sustainer engines operate until it reaches peak velocity. . This phase can take 3 to 4 minutes for a solid rocket (shorter for a liquid-propellant rocket), the altitude at the end of this phase is 150–200 km, and the typical burn-out speed is 7 k

The second phase might be against the defenders' artillery batteries and the third against their front-line trenches to drive them back just before the infantry assault on those positions. The last phase was typically a creeping barrage that moved forward of the advancing infantry to quickly bombard positions just before they are attacked. The ...
