Evaporation

Although they may be oddly shaped, volumetric and Erlenmeyer flasks are closed-end air columns, and they abide by the conventional rules of resonance. When a rubber stopper is inserted into a flask some air is forced out of the flask, and the stopper seals the flask so the air cannot get back in. This creates an area of low pressure within the flask. When the stopper is quickly pulled out of the flask, the air rushes back into the flask because the pressure of the atmosphere is higher than the…

Introduction In order to create a compound, there must be two or more atoms that bind together. These atoms may be made up of different elements, or some may be the same. There are two main ways that atoms bind together- covalently and ionically. In a covalent bond, two non-metals of similar electro negativities come together to share electrons with each other. These electrons come from the outer-valence shells, and are shared in a way so that both electrons can have satisfactory shells,…

My Fellow Americans, I am sure that many, if not all, of you are aware of the debate surrounding climate change. The issue has been well-covered in the media, with positions being taken on all sides of the issue. There are those that have sounded the alarm, warning of impending doom should we fail to act. Some have argued that climate change is but a passing fad, a nonissue that poses no real threat to our way of life. Others still have carved out positions in between these two extremes. Much…

man-made lake. The ecosystem had to go through a dramatic change in balance. For example, the water levels rising cause a drop in temperature which many warm-water fish could not comprehend, and almost pushing them to extinction. Another point was evaporation of 350 billion gallons of water on Lake Mead surface area of (640 sq km) because of the area being evaporated erosion had…

The Atlantic Ocean is the second largest ocean out of the five oceans and stretches east of North and South America to west of Europe and Asia. Its climate consists of ocean currents, which are dependent on the uneven heating of the Earth’s surface and continents/landmasses nearby. Ocean currents transport heat energy within the biosphere, with surface ocean currents warming or cooling the air above them, affecting the land nearby. Surface water is affected by wind currents, while deep ocean…

Hurricane, a storm with a violent wind, particularly a tropical cyclone in the Caribbean. The term, Hurricane, is a term only really used when a large storm takes place and has been formed over the Atlantic or Eastern Pacific Ocean. Hurricanes have been reported since the 1900's and are still being reported to this day. "On August 30th, 2017, a Hurricane named Irma formed in midst of the Atlantic Ocean and stretched into parts of Florida. This hurricane lasted 15 days, ending on September 13th,…

Differentiate between the saltwater of the ocean to the freshwater of lakes and rivers. 7. Compare and contrast the spatial difference of the ocean water to that of the continents as it relates to the Earth. MEAP VOCABULARY - ocean, sea, continent, theory, freshwater, salinity, lake, river, underground water, oceanography. MATERIALS: text book, transparencies, large wall mounted world map, ocean informational handouts, “Label the Earth’s Oceans” worksheets, “Continents and…

Oil (or petroleum) is a very important thing to us. We use it every day. We use a lot of it in just a single day. Our life depends on oil. It may not be the only thing but it is one of the most important. My report is on oil and how it affects us. Oil is a fossil fuel. It was created millions of years ago from the remains of prehistoric organisms at the bottom of lakes or oceans.10,9,17 Fossil fuels are formed from the remains of dead plants or animals.The plants or animals were called plankton…

 Second Law: The mass of substance produced in electrolysis directly proportional to its equivalent mass. W1 / E1 = W2 / E2 = W3 / E3...  Third Law: The mass of a substance produced in electrolysis is directly proportional to the number of electrons per mole needed to cause desired change in oxidation state. Conductivity When voltage is applied to the electrodes immersed into an electrolyte solution, ions of electrolyte move, and thus, electric current flows through the electrolytic…

have created the environment in which our children and grandchildren are going to live”’, says Tim Barnett of the Scripps Institution of Oceanography (Achenback and Heidi 2). Greenhouse gases driven temperature rise would result in an increase in evaporation of methane, another greenhouse gas, which is dissolved in lakes, and otherwise emitted at a slower rate (“Human and Natural”). The methane gas, like any other greenhouse gases would accumulate in the earth’s atmosphere, and trap the…
