What causes rain to fall?

Rain is a form of precipitation (weather that falls from the sky, basically). It is caused when clouds (made of water vapor) absorb too much moisture.See all results for this questionWhat are the different types of precipitation?The main forms of precipitation include drizzle, rain, sleet, snow, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates.Reference: www.eartheclipse phase precipitation/geography/different-types-of-precipitation.htmlSee all results for this questionWhat are some examples of precipitation?Rain is precipitation. noun.

The Mechanism of Phase Precipitation in A286 Superalloy phase precipitation

May 29, 2013 · In this research, the mechanism of eta (-Ni3Ti) phase precipitation in iron-nickel-based A286 superalloy was assessed during aging heat treatment in the temperature range between 650 and 900 °C for the times of 1-30 h. Optical microscopy, scanning electron microscopy, differential thermal analysis, and x-ray diffractometry were used to describe the phase transformation.Sensitivity of Precipitation Phase over the Swiss Alps to phase precipitationThe precipitation phase highly depends on the melting rate of solid precipitation, which is associated with the energy available for the melting. It is mainly determined by the air temperature and by the air moisture (see, e.g., Szyrmer and Zawadzki 1999). Therefore, a drier air will lead to a slower melting rate, which increases the probability of snow or mixed precipitation at temperature higher than 0°C.Review: precipitation in austenitic stainless steelsAn in-depth review of -phase precipitation in Cr-Ni austenitic steels has been done by Barcik . Sigma phase precipitates first on triple points then on grain faces. After long term ageing at high temperature, it also forms on incoherent twin boundaries and intragranular inclusions.

But, matter on Earth exists mostly in three distinct phases: gas, liquid and solid. A phase is a distinctive form of a substance, and matter can change among the phases. It may take extreme temperature, pressure or energy, but all matter can be changed. There are six distinct changes of phase which happens to different substances at different temperaturSee more on study phase precipitation
