Boyle’s Law Lab Purpose: To determine the relationship between pressure exerted and volume of a gas. Materials: Lab simulation. Procedure: 1. Open animation file 2. Modify the number of books that press down on the piston starting from 0 books and increasing by 1 each time until 19 books. 3. Record the pressure (# of books) and volume for 19 different pressure values. 4. Record those values in a table 5. Using the data‚ plot a graph of pressure in function of volume. Conclusion:

were not so happy. There were those who wanted to stop funding the Germans with the proceeds from their beer. There were those wanted the opportunity to tell differing views on creation in their classrooms. Also‚ most notably‚ there were women who were tired of being forced to be housewives and demanded to be treated as equals among the men. The crisis in values that occurred during the 1920’s‚ as insignificant as it might seem today‚ forced Americans to reshape their way of thinking and make changes

Sports have always been an important part of people’s lives and a way for them to relax. The 90’s was a decade of unbelievably talented athletes and major icons. Michael Jordan started his fame in basketball and is now known as one of the greatest basketball players of all time. In 1995‚ at age fourteen Serena Williams became a top competitor and became a pro in the game of tennis. Tiger Woods became the first golfer in history to win the U.S. Amateur title for three consecutive years. The 1992 Dream

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential

Thermodynamics- Enthalpy of Reaction and Hess’s Law Objectives: 1. To calculate the heat of reaction of a given reaction using the concepts derived from Hess’s Law. Pre-lab Questions: 1. Define Heat of Reaction. The enthalpy change associated with the completion of a chemical reaction. 2. Define Specific Heat. The energy it takes to raise the temperature of 1 gram of a substance by one degree Celsius. 3. Calculate the heat of reaction assuming no heat is lost to the calorimeter. Use correct

P2 andP3? Yes there were notable differences in the appearance of P2 and P3. P3 had a light brown colouration and was more compact whereas P2 had a dark brown creamy colouration. 4) Define the beer lamberts law and briefly explain why absorbance has no units. In Spectroscopy‚ Beer-Lambert’s Law describes the quantitative relationship between the absorbance of light energy‚ the concentration of the sample solution and the length of the path through the sample. This means that the amount of

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding
