PH is a measure of how acidic<span>/basic water is. The range goes from 0 - 14, with 7 being </span>neutral<span>. pHs of less than 7 indicate </span>acidity<span>, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl </span>ions<span> in the water.</span>

Relative humidity. A psychrometer has two thermometers, one for dry-bulb temperature and the other wet-bulb temperature.
<span>All the options (heat, pressure, deposition and chemical environment) are correct.<span>
Metamorphic rocks are formed when pre-existing rocks are subjected to heat, pressure and hot mineral rich fluids which cause physical, chemical and mineralogical changes to the rock. Metamorphic rocks are grouped by chemical, texture and mineralogy. The common metamorphic rocks include schist, marble, and gneiss.
