A vogadro was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for three years after. In 1800, he began to take private lessons in mathematics and physics and decided to make the natural sciences his profession. He was appointed as a demonstrator at the Academy of Turin in1806 and the Professor of Natural Philosophy at the College of Vercelli in 1809, and in 1820, he was appointed the professor of mathematical physics. He was a physics professor but he also experimented in chemistry using mathematics to base most of his findings.
Avogadro is well known for his hypothesis known as Avogadro's Law. His law states that at a given temperature, equal volumes of gas contain

For gases this can be done by using 22.4 liters at STP(1 atmosphere and 223 Kelvin, 0 deg. Celsius). Avogadro's number is most reliably determined by X-ray diffraction of …show more content…
Cannizarro later used Avogadro's hypothesis to develop a set of atomic weights based on 116 of the weight of oxygen. This was a basis for finding much more accurate estimates for Avogadro's number. Reasonable values were made in the late 1800's from sedimentation equilibrium of colloidal particles. Millikan's oil drop experiment in the 1900's gave even more accuracy and was cited in most chemistry text books 50 years ago. Text books in 1958 gave Avogadro's number as 6.02 x10 to the 23rd.
The current value is 6.0221367x10 to the 23rd power. Amedeo Avogadro proved to be one of the greatest scientists to ever live. If it had not been for Avogadro and his findings there is no way that Chemistry in general would be where it is today. Avogadro's work was recognized nearly fifty years after he had made his hypothesis. Two years after his death, his colleague showed how they could use Avogadro's number to solve many of the problems in chemistry. Avogadro's work also helped other scientists to solve more problems and develop more theories.<FONT
He began writing about his hypothesis/ idea in 1864-65, and published the results in 1866. It was not until 1900 that his published findings were
The book written by Thucydides, History of the Peloponnesian War, contains two controversial debates between distinguished speakers of Athens. The two corresponding sides produce convincing arguments which can be taken as if produced as an honest opinion or out of self-interest. The two debates must be analyzed separately in order to conclude which one and which side was speaking out of honest opinion or self-interest, as well as which speakers are similar to each other in their approach to the situation.
The Peloponnesian War could easily be considered one of the most life changing and significant wars that occurred in classical Greece. It was fought between two empires which originally stood together against a common enemy, the Persians. However, once this common enemy was defeated, Sparta and Athens began to become great rivals vying for control of Greece. This resulted in the First and Second Peloponnesian Wars, which saw the rise and fall of the Athenian Empire. Sparta eventually rose to be the victor with the assistance of their former enemy Persia, but the era city-states would not live on for very much longer. The Peloponnesian Wars should be studied, because it details the rise and fall of one of the greatest city-states in Greek history.
Throughout the Ancient Greek world, there have been many wars and standoffs. However, there has been only one which changed the course of Greek history forever; the Peloponnesian War. Caused by the growing tension between Athens and Sparta, it came and left, leaving only destruction in its wake. The defeat of Athens in the Peloponnesian War caused the downfall of Greece, and the end of the Classical Age.
In this lab, we are finding the number of molecules in one mole. To do so we use Avogadro's number as a reference. Avogadro's number is 6.02 x 10^23 and the final calculation at the end of the experiment should be close to this number. Avogadro's number represents that if there is an equivalent number of gases that are present at the same temperature they will all contain the same number of molecules as each-other. Using the calculations given a number of molecules in a mole of oleic acid can be found.
...e hoslities and the causes of the eventual war. However, historians will continue to debate the level of influence that particular factors and events played on the final lead to war, due to the complex nature of alliances and aggressive mindsets held in the Greek world.
The Peloponnesian War is the conflict between the pelopoponesians league led by Sparta and the Delian league, led by Athens. Much of our knowledge on the causes and events of the Peloponnesian War, depends on the Athenian Thucydides 460-400 BC, writer of the History of the Peloponessian War. He servd as an Athenian commander in Northern Greece during the early years of the war until the assembly exiled him as he lost an outpost to the enemy. During this exile, he was able to interview witnesses on both sides of the conflicted. Unlike Heredotus he concentrated on contemporary history and presented his account of the war in an annalistic framework that only occasionally diverts from chronological order. In his account, he discuses the precursors to the war, including the 30 years truce and revolutions, such as the stasis in Corcyra. When looking at wars, the primary focus is normally the fighting itself, such as what we see for World War II. However, it is important to look at the anatomy of war, meaning what effect the war has on the people who are experiencing it first hand, and the consquences that the conflict has on the rest of the world. Therefore in this essay I shall discuss, drawing directly from Thucydides, The History of the Peloponnesian War, how the civilians reacted to the war, their involvement and socio economic factors. Furthermore, the first section of my essay shall focus on the direct effect of war on the people, regarding the plague, and violence and hopelessness that was experienced. Then I shall go on to discuss more general effects of the war and how it affected the Greek world, discussing the social and economic losses that occurred such as the cost of the war in attica, the coup d’etat that occurred in gove...
This showed that dissolved gases were mechanically mixed with the water and weren?t mixed naturally. But in 1803 it was found that this depended on the weight of the individual particles of the gas or atoms. By assuming the particles were the same size, Dalton was able to develop the idea of atomic weights. In 1803 this theory was finalised and stated that (1) all matter is made up of the smallest possible particles termed atoms, (2) atoms of a given element have unique characteristics and weight, and (3) three types of atoms exist: simple (elements), compound (simple molecules), and complex (complex molecules).
The Athenians were fighting battles that were not meant to be fought. There were great droughts in sundry places and consequent famines, and that most calamitous and awfully fatal visitation the plague. All this came upon them with the late war, which was begun by the Athenians and Peloponnesians by the dissolution of the thirty years truce made after the conquest of Euboea. This is a direct and distinct blame of the war toward the Athenians. The famines, plagues, and diseases were just a sum of the long-term and short-term effects of the Peloponnesian War.
War has been around for the past couple of centuries now. A question that comes out of many people’s mouths’ is, “Is war the answer?” Centuries ago people may have agreed, however for nowadays maybe not so much. In the BC time era, men were trained to fight with their bodies as their weapons and to take no mercy when it comes to the enemy. If one were to dishonor their kind or betray them, the consequences would be a painful death. The following information portrayed in this essay is to discuss the causes of the Peloponnesian War, who won the war and why they conquered a nice victory.
Additionally, in the book US FOREIGN POLICY, Michael Cox (2012) concluded that “China’s peaceful rise has largely consoled its neighbors and the United States that it remains a status quo power. However, as it has risen, there are some (perhaps an expanding number) who predict this will lead to increased regional and global competition” (p.266). Clearly, Michael Cox indicated the point that there might be more competitions in the future relation between China and the rest of the world no matter China rises peacefully or not. In particular, China and the United States will face many intense issues since they are the two giants in th...
The Peloponnesian War (431-404 B.C.) was a conflict between the Athenian Empire and the Peloponnesian League led by Sparta that resulted in the end of the Golden Age of Athens. The events of the war were catalogued by the ancient historian Thucydides in The History of the Peloponnesian War. Thucydides’ writings showed the ancient Greek belief that there is a parallel between the city-state and the character of its citizens; in order for the city-state to be successful, its citizens must be virtuous. Thucydides did not believe that the true cause of the Peloponnesian War were the immediate policies of the Athenian Empire against the city-states in the Peloponnesian League but rather the fundamental differences in the character of the two city-states
Human trafficking is a form of slavery, forcing victims to engage in sexual activities and labors against their will. These activities can be taken place through force, fraud, or constraint. Human trafficking is not just affecting one group of people, it is a worldwide issue, affecting all different ages, genders, ethnicities, and socio-economic backgrounds. Human trafficking is such an immense problem, apprehending the true size, knowing how to help, and how to keep the issue from reoccurring. Human trafficking is and is still becoming such a serious issue that something needs to be done about.
All these factors go hand in hand to solidify warfare in Ancient Greece as not only a constant in their society, but nearly a staple. Without the influence of war, ancient Greece would not be near as significant in history. Spartans and Athenians alike relied on war not only for defence, but identity. Warfare in ancient Greece wasn’t only a common occurrence, but a heavy influence for their identity and ways of life, even
