When the salt is added, the phenomenon known as “boiling point elevation” occurs. Which, involves the old school chemistry the solute, the solvent, and the solution. Chefs…

In this lab we will be testing the water quality of the Lewis and Clark Lake. We will be testing to see if the water is good quality and good for the fish and creatures that need that water to live. The first step is to extract the water from the lake and analyze the way it looks. We should write down the description of the water. The second step is to take it to the lab to test the water for pollutants and to test the quality of the water. Ph. is a measure of the hydrogen ion concentration of…

currently. Most water on earth is found in oceans and is salty, while most water that is used by human needs to be freshwater, whether it be for drinking, agriculture or cooking. Our freshwater sources are mainly frozen in ice caps and glaciers, but these sources are not always accessible by people depending on their location. In much of the continental United States, the main source of freshwater is taken from our groundwater sources. Maintaining the quality of this critical source is key to…

“with the world population projected to increase by an additional two billion (2×〖10〗^9) people by the year 2030 (United Nations 1998), finding ways to satisfy humanity’s water demands while at the same time protecting the life-support functions of freshwater systems now ranks among the most critical and difficult challenges of the 21st century” (Postel 941). Postel does not just state her exigence once but reiterates it throughout the entire article. Also notice her use of logos and ethos to…
