Three Great Achievements in Ancient Egypt essays

Three Great Achievements in Ancient Egypt essays Denial...its not just a river in Egypt is a statement we have probably all uttered. However, we cannot deny that there were many great things achieved by the amazing civilization of ancient Egypt. In this essay, we will examine three of the achievements that still fascinate us today, thousands of years later, the religious beliefs, the development of hieroglyphic writings, and the mummification of the dead. Religious Beliefs The Egyptians had many cults in the early days of Egyptian religion with over 2,000 gods and goddesses. These gods and goddesses had an indirect relationship with the Egyptian people. They would most often be animal gods like Anubis (the Jackal) who was linked with the dead and funeral arrangements. Jackals were often seen on the outskirts of the desert where the Egyptians buried their dead. In the development of early Egyptian religion, people in one region of Egypt often worshiped different gods than those in another region. They would build shrines inside their home to gain favor with certain gods to help in their daily life, for example, Thoth the god of scribes. In the Dynastic period gods and goddesses began to take a more humanistic look with human bodies but kept animal features like the god Taurt who had the head of a hippopotamus, the tail and back of a crocodile, and claws like a lion. There were very few animal gods still being worshiped by this period. One exception was Apis (the Bull) in Memphis. By the end of the Early Dynastic Period, when the two regions of Egypt were unified, a national religion began to form from the many tribes and regions. Of course, there were many inconsistencies and variations as the different priests were trying to systematize the gods, goddesses, and myths among the population. The next evolution in the development of ancient Egyptian religion happened at the time of the Old Kingdom during the 5th Dynasty....

Boyles Law Definition in Chemistry

Boyle's Law Definition in Chemistry Boyles law states that the pressure of an ideal gas increases as its container volume decreases. Chemist and physicist Robert Boyle published the law in 1662. The gas law is sometimes called Mariottes law or the Boyle-Mariotte law because French physicist Edme Mariotte independently discovered the same law in 1679. Boyles Law Equation Boyles law is an ideal gas law where at a constant temperature, the volume of an ideal gas is inversely proportional to its absolute pressure. There are a couple of ways of expressing the law as an equation. The most basic one states: PV k where P is pressure, V is volume, and k is a constant. The law may also be used to find the pressure or volume of a system when the temperature is held constant: PiVi PfVf where: Pi initial pressureVi initial volumePf final pressureVf final volume Boyles Law and Human Breathing Boyles law may be applied to explain how people breathe and exhale air. When the diaphragm expands and contracts, lung volume increases and decreases, changing the air pressure inside of them. The pressure difference between the interior of the lungs and the external air produces either inhalation or exhalation. Sources Levine, Ira. N (1978). Physical Chemistry.
