There are three mechanisms with which supersaturation occurs&colon; precipitation, nucleation, and metastable. A crystallization phase diagram shows where undersaturation, saturation, and supersaturation occur at certain concentrations. This occurs in superheating, supercooling, and supersaturation, for example. Net condensation of the vapor requires supersaturation, a partial pressure greater than its vapor pressure. As the system comes into equilibrium, the level of supersaturation decreases, favouring crystal growth. On reaching supersaturation, the source solidifies and grows outward from the nanocluster. In PLD, a large supersaturation occurs on the substrate during the pulse duration. The study of supersaturation is also relevant to atmospheric studies. This phenomenon is known as in vivo supersaturation. This is a condition known as supersaturation. Such critical size is dictated by many different factors (temperature, supersaturation, etc.). There are no instruments to take measurements of supersaturation in clouds. The time it takes for the supersaturation to dissipate is called relaxation time. Supersaturation and subsequent deposition of the inorganic salts occur. Values for critical supersaturation derived from this experimental work were different for each tissue compartment.
