(1) Evaporation: Surface Area: Evaporation is surface phenomenon.Greater is surface area greater is evaporation and vice versa.For example‚ sometimes a saucer is used if tea is to be cooled‚ quickly.This is because evaporation from the larger surface area of saucer is more than that of the smaller surface area of the tea cup. Temperature: At high temperature‚ rate of evaporation is high because at high temperature

Wilson’s Fourteen Points vs. Treaty of Versailles World War One was a tragedy that affect not one but many countries. It brought destruction‚ starvation‚ enemies‚ and death not only of soldiers but of normal civilians. There were two proposals created to end World War One: Wilson’s Fourteen Points and the Treaty of Versailles. They were both created to bring peace between the countries. However‚ they both had their positives and negative effects. Wilson’s Fourteen Points would have more independent

This paper is a full determination for certain chemicals and their boiling points. It lists some already but given the atomic numbers of any material this project includes a conversion and calculation chart to find the freezing point of most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step

LECTERUR : EXPERIMENT 4 DETERMINING MOLECULE WEIGHT BY FREEZING POINT DEPRESSION METHOD STUDENT NAME : ID : LAB PARTNERS | | INTRODUCTION According to Anne‚ n.d‚ the freezing point of a liquid is decreased by adding to another compound to it. This is known as freezing point depression. The pure solvent will have higher freezing point than the solution. Colligative property of matter can explain more about freezing point depression. Whereas‚ colligative properties depends on the number

Experiment 3 Colligative Properties Freezing-Point Depression and Molar Mass By‚ Andrew Klingsporn Joby J. Chem 212 Dr. Chandana Meegoda 2/11/2009 Purpose The purpose of this experiment is to determine the Molar Mass of an unknown substance using its freezing point depression. Introduction There are two types of mixtures; homogenous and heterogeneous. Homogenous mixtures have components that are uniformly mixed‚ while heterogeneous mixtures do not. A solution is a homogenous mixture

Fourteen Points was a name given to the proposals of President Woodrow Wilson designed to establish the basis for a just and lasting peace following the victory of the Allies in World War 1. The 14 proposals were contained in Wilson’s address to a joint session of the US Congress on January 8‚ 1918. In summary‚ the 14 points were as follows : 1. abolition of secret diplomacy by open covenants 2. freedom of the seas in peace and war‚ except as the seas may be closed in whole or part by international

Woodrow Wilson’s decision to give his Fourteens Points speech contributed to the end of World War I‚ was the basis for many peace treaties and paved the road for future nations and alliances. "Covenants of peace be quickly arrived at so that this war can end and future nations can begin." These are some of the words of Woodrow Wilson said when he delivered the powerful Fourteen Points speech at the joint session of Congress and many other important meetings including the Paris Peace Conference

the tipping point of the United states no longer considered being an isolated nation ? My personal opinion on that question is the cash and carry act of 1939‚ this act is what started the American people to really look at what was happening. The cash and carry act was Roosevelt’s idea and he was very supportive of the United States joining the war. Everything after this would lead the Americans to understand the need for a democratic government and the end of unfair views. At the point where the
