Geography has affected regions and civilizations in many ways. The Nile river in Egypt improved and helped the economy in to grow in several ways. Just as the mountains in ancient Greece took part in the growth of the economy and nation as well. The Nile River had a huge impact on the rise of Ancient Egypt. The Nile River is located in Africa which flows from Egypt and through the Mediterranean sea. It was known to be the longest river in the world, resulting in constant flooding. Many people might look at this flooding situation in a bad way, but as the flood was sweeping through the land it left behind rich and fertile soil which can be used for farming. The farmers would also use an irrigation ditch which will store the flooded water and be used when its needed, such as in really hot days or as bathing water. Prosperity from the Nile didn't stop there. It was a food source, such as fishes and birds, as well as the papyrus that grew along the Nile which was then used as paper. What the Nile River was mostly used for, was for trading many goods between Egypt and many other countries near it. Without the Nile River, Egypt would just be a big desert with no resources or goods.

Just as the Nile was good for trade, so was the mountains in ancient Greece. Even though the mountains was known as a barrier that isolated many cities it was good at the same time because it helped the Greeks to seek more knowledge and to look beyond those mountains and to get the resources they

Essay on Ideal Gas Law and Gas

Gas Laws Elements that exist as gases at 250C and 1 atmosphere Physical Characteristics of Gases • Gases assume the volume and shape of their containers. • Gases are the most compressible state of matter. • Gases will mix evenly and completely when confined to the same container. • Gases have much lower densities than liquids and solids. Force Pressure = Area Units of Pressure 1 pascal (Pa) = 1 N/m2 1 atm = 760 mmHg = 760 torr 1 atm = 101,325 Pa Barometer 10 miles 4 miles Sea level…

Gas Law Essay

Gas Laws -study the relationships that exist between pressure, volume, temperature and amount (moles) of gas. 1. Boyle’s Law * Pressure-volume relationship * At constant temperature and amount, the pressure and volume of a gas are inversely proportional. * As pressure increases, volume decreases. * P1V1=P2V2 2. Charles’ Law * Temperature-volume relationship * At constant pressure and amount, the temperature and volume of a gas are directly proportional.…

KMT Gas Laws Essay

Gas Laws – Explained Using Kinetic Molecular Theory Pressure varies inversely with the volume of a fixed amount of gas at a constant temperature --- this is known as Boyle’s Law of gases. Use a molecular model to explain pressure A gas is composed of a large number of particles in rapid motion. Each particle occasionally collides with a wall of the container. As a result of that collision, the particle exerts a force on the wall. This creates pressure (ratio of force to area). Use a molecular…

Essay on Ideal Gas Law lab

still a few scattered bubbles and all of the Alka-Seltzer has gone into the water. The balloon is standing erect and slightly firm to the touch. There is water inside the balloon. The bubbling has stopped. When the balloon was cut a small whoosh of gas could be heard escaping. The balloon returned to normal size. On the inside of the balloon there are trace remains of Alka-Seltzer powder. Mass measurements: Mass (±.05g) Mass of flask with water, balloon, Alka-Seltzer 396.8g (±.05g) Mass of items…

Things: Ideal Gas Law and Temperature Essay

Exploring the Properties of Gas Shawna Hendricks CHM 144 C Robert Baum Colleen Heffner and Andrew Flannery Abstract: The hypothesis of whether or not the relationships between the properties of gases will all be direct is experimented. This was done by experimenting three variables of properties of gases such as temperature, pressure, and volume. Temperature and pressure were tested together while volume was kept constant, then the relationship…

Essay about Determining Molar Volume of a Gas

Volume of Gas Using Magnesium and Hydrochloric Acid and Demonstrating Boyles Law Taylor Payne Abstract: In this experiment we combined a strip of magnesium with hydrochloric acid in a buret and measured the amount of hydrogen gas the reaction produced. We also tracked the pressure inside a syringe as the volume of the syringe increased and decreased. Introduction: The moles and density of the hydrogen gas that is produced in this experiment can be calculated using the combined gas law equation…

Avogadro's Law Lab Report

In this experiment, the molar volume of Hydrogen gas was measured by proving Avogadro’s Law. Avogadro’s law or principle was explained as: “Equal volumes of gases at the same temperature and pressure contain equal number of particles.” (Dingrando, Tallman, Hainen, Wistrom, Chemistry: Matter and Change) Avogadro’s Law is related to the molar volume, which is the volume of one mole at standard temperature and pressure. Standard temperature and pressure (STP) were established as 0.00oC or 273K…
