Boyles’ Law Use Boyles’ Law to answer the following questions: 1) 1.00 L of a gas at standard temperature and pressure is compressed to 473 mL. What is the new pressure of the gas? 2) In a thermonuclear device‚ the pressure of 0.050 liters of gas within the bomb casing reaches 4.0 x 106 atm. When the bomb casing is destroyed by the explosion‚ the gas is released into the atmosphere where it reaches a pressure of 1.00 atm. What is the volume of the gas after the explosion

1st‚ 1915. Its name was the RMS Lusitania and its sinking‚ which occurred six days later on May 7th‚ 1915 is usually credited as a main reason why the United States decided to enter World War I (Unknown‚ OL). The sinking of this liner involves a sequence of events that led to its sinking‚ main participants and groups that were involved and affected by the sinking‚ and it created a great significance and importance after it was over. The sinking of the Lusitania occurred because of a series of events

HRIS- THEORETICAL DIMENSIONS HUMAN RESOURCE INFORMATION SYSTEM The Human Resource Information System (HRIS) is a software or online solution for the data entry‚ data tracking‚ and data information needs of the Human Resources‚ payroll‚ management‚ and accounting functions within a business. Normally packaged as a data base‚ hundreds of companies sell some form of HRIS and every HRIS has different capabilities. Pick your HRIS carefully based on the capabilities you need in your company.

The Titanic was one of the worst cruise ship disasters know in the world. The Titanic hit an iceberg and sank on 15 April 1912. Over 1500 passengers died as a result of the Titanic sinking. To understand why the Titanic sank‚ one has to apply the three accidents theories to the disaster and then determine what theory applies the most. The first theory is natural accidents theory. Natural accidents theory states that every system fails at some point depending on how the systems is designed. The way

RSR The Sinking of the Aragon With the outbreak of world one war the royal mail moved its home port to Newport‚ South Wales. However the Brittish government was in dire need of battle ships to strengthen their naval force. Many ships were converted from simply postal delivery vessels into war ready troop carrying ships. One of these ships was the Aragon The Aragon built in harland and wolf in Belfast

Purpose and Method: The purpose of this experiment was to understand Boyle’s Law. In the experiment the pressure in the system under constant temperature and mass was used to confirm if the laws are true. Boyles law relates pressure and volume while all other factors are consistent and states: for a fixed amount of gas kept at constant temp‚ the product of the pressure of the gas and its volume will remain constant if either quantity is changed‚ or where k is constant. The experiment consisted

at 11:40 p.m. on April 14‚ 1912. Estimated to be able to stay afloat for 2 days under the worst scenario‚ the ship sank in less than 3 hours [Gannon‚ 1995]. Main Cause for Sinking The iceberg created a 300-foot gash in the Titanic’s hull above and below the waterline. Structural Errors That Accelerated the Sinking Steel brittleness Tests on Titanic’s steel showed that the steel had high sulfur content‚ which increases the brittleness of steel by disrupting the grain structure [Hill
