Ionic and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water to clean the probe

* Cube In geometry‚ a cube is a three-dimensional solid object bounded by six square faces‚ facets or sides‚ with three meeting at each vertex. As the volume of a cube is the third power of its sides ‚ third powers are called cubes‚ by analogy with squares and second powers. A cube has the largest volume among cuboids (rectangular boxes) with a given surface area. Also‚ a cube has the largest volume among cuboids with the same total linear size (length+width+height). * Parts:

The vapor pressure of a liquid is the equilibrium pressure of gas molecules from that liquid (i.e.‚ the results of evaporation) above the liquid itself. A glass of water placed in an open room will evaporate completely (and thus never reach equilibrium); however‚ if a cover is placed on the glass‚ the space above the liquid will eventually contain a constant amount of water vapor. How much water vapor is present depends on the temperature‚ but not on the amount of liquid that is present at equilibrium

Comparing Dissolved Oxygen in the Woods‚ the Wet Area near the Succession Plots‚ the Winthrop Lake‚ and the Wetlands Isis Nelson Dr. McCulloch BIOL 203 March 8‚ 2013 Abstract Title: Multiple comparisons between different locations with dissolved oxygen. Is there a difference in the dissolved oxygen in the wetlands‚ woods‚ lake‚ and water area near the succession plots? Dissolved oxygen is the amount of oxygen that appears inside water.

Global Service Department Business Opportunity Analysis CASE 3. Dogfight over Europe: Ryanair 1) Do you believe Ryanair’s entry into Dublin-London route was successful? Yes‚ Ryanair’s entry into Dublin-London route could be counted successful. Ryanair‚ which has been operated since 1985‚ is a small and rather domestic company compared to Aer Lingus and British Airways (BA). They will operate a turboprop that contains 44 seats‚ that takes 4 round trips per day. Unlike the two giants‚ Ryanair is not

What is Electricity? Electricity is one of the most powerful forces in our lives. As a matter of fact‚ it can even kill you. The most vital part of electricity is called electric energy. This is what we commonly think of when we hear the word electricity. “Electricity” reminds us of anything that we plug into an electrical outlet in order to make it work‚ such as lights‚ refrigerators‚ video games‚ microwaves‚ and computers. Scientists discovered ways to produce electric energy in large amounts

Liquid Nitrogen Liquid nitrogen is nitrogen in a liquid state at a very low temperature. Its chemical formula is N2. Manufacturing of Liquid Nitrogen Liquid nitrogen is made by cooling and compressing air straight from the atmosphere. The type used to produce large amounts of liquid nitrogen looks vastly different but really happens is that air squashed and cooled . When you squash it‚ air molecules are forced closer together. If you also cool it down the molecules can slow down enough to
