We started our separation using vacuum filtration, first with ethyl acetate, and then water. ... Water was not used first in our separation technique because one of our organic compounds, m-nitroaniline, were slightly soluble in water (we guessed that we had m-nitroaniline and naphthalene due to our soil's distinctive color and odor). Had we used water first, the liquid layer from the separation would be composed of both inorganics and some organics, requiring us to perform extra separation techniques again on the water solution. ... The resulting solution consisted of m-nitroalinine diss...

The early Greeks considered "air" to be one of four elementary substances; along with earth, fire, and water, air was viewed as a fundamental component of the universe. ... For example, variations in water vapor in the atmosphere are familiar to us as relative humidity. Water vapor, CO2, CH4, N2O, and SO2 all have an important property: They absorb heat emitted by Earth and thus warm the atmosphere, creating what we call the "greenhouse effect." ... Some scientists call the tropopause a "thermal layer" or "cold trap" because this is a point where rising water vapour cannot go higher because it...
