waterborne outbreaks the pathogen does not always have to come from drinking the contaminated water because many different disease-causing microbes can be found in a tiny sample of unsafe water (4(pg.4)). Safe water can be limited once a natural disaster happens, and unsafe water, filled with disease causing microbes, is lurking all around. The disease most commonly associated with the consumption of unsafe water is the diarrheal disease, which can be caused by a few different microbes. Most cases of

5. Calculate the mass of the water by subtracting “Mass A” from “Mass B.” Record the mass of the water in Data Table 4. 6. Pour the water down the drain and fully dry the graduated cylinder. 7. Repeat steps 2 through 6 for the isopropyl alcohol. 8. Calculate the densities of both the water and the isopropyl alcohol and record in Data Table 4. 9. The accepted value for the density of water is 1 g/mL and the accepted density for isopropyl

made by scientists over the last thirty-five years all agree upon the notion of shrinking, and or retreating of the ice sheets. The melting of ice sheets has powerful implications for the millions of people who depend on glacial melt for drinking water and the millions of people who will be displaced by the sea level rise occurring as a direct result of the melting. The observations of ice melting also show that the rate at which the ice is melting is accelerating. Mountain glaciers around the world

took place over 200 years ago. Thinking about the effects that those discharges might have in future, one has to take into consideration that at least the pH – level of water has changed from 3,3 pH (around 1800) to 6,1 pH (today) (Wilkinson 2011); an improvement can be recognized. Nonetheless, it is obvious that drainage water still has a great impact to organisms. It is necessary to think of methods to stop this pollution as it could lead to an extinction of organisms. 7.

Christensen English 102 September 16, 2012 Shannon Lewis Harvesting Natural Gases I. Introduction A. Although natural gas is the next step to our clean energy initiative, the lack of regulations on fracking is leading to air and water pollution, droughts and undisclosed chemicals which are used in the process. II. What is the Fracking? A. Fracking is a process to harvest Natural Gases from the earth core. 1. There are two different processes of

to chemical and mechanical weathering. Rainfall, biologic activity, abundance of openings, composition of the rock, amount of vegetation, temperature, and tectonic settings are important factors in the weathering process. External forces like wind, water, and ice are constantly causing changes in the surface of rocks. These activities are cutting some material away while depositing other materials here and there. This process landscapes the Earth as we see it. Weathering falls into two categories,

found experimentally to have a much lower ?T than n-Pentane, it is because it has much higher IMF of attraction due to Hydrogen Bonding compared to the n-Pentane. It also benefits from dipole-dipole forces due to its polarity as a molecule. 5. Water had the lowest

were to measure and record the mass of a beaker, then transfer about 1 gram of the salt mixture into the beaker, measure, and record the combined mass. Then, we had to fill a 400-ml beaker with deionized water and test it to make sure that the ph was just basic. We then combined the deionized water and salt by adding about 150ml of the deionized
