Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

recent decades when people were trying to erase Pereira’s work. In “Erasing Pereira”‚ Alan Hess gives his opinion while addressing‚ “What do California’s cultural institutions have against William Pereira?”. He begins his article by stating that Pereira had gained his name because of his work in the Orange County area‚ which later had been faded and people were misinterpreting the vision of the great architect. Hess says that Pereira had designed UC Irvine with meticulous planning and a very revolutionary

Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample

Objectives: 1. Distinguish between system and surroundings. 2. Distinguish between heat energy and temperature. Name the SI units of temperature and thermal energy. 3. Calculate the heat content (thermal energy) of a substance using its specific heat‚ temperature and mass. 4. Solve calorimetry problems. 5. Name the energy associated with a change of state and calculate the energy required to change a given mass of substance from solid to liquid or liquid to gas. 6. Describe the changes in the microscopic

In 1916‚ Henri Fayol published his "14 Principles of Management" in the book "Administration Industrielle et Generale." Fayol also created a list of the six primary functions of management‚ which go hand in hand with the Principles. Fayol’s "14 Principles" was one of the earliest theories of management to be created‚ and remains one of the most comprehensive. 14 Management Principles developed by Henri Fayol are : 1. Division of work : Work should be divided among individuals and groups

Alixandria Zeidel Physics 131 – section LZ Hasbrouck 208 10/01/14 Forces and Newton’s 2nd law Abstract The purpose of this lab was to learn about how force influences acceleration. A hanging mass is tied to a frictionless glider and the mass is dropped. While the glider is being pulled by the mass it is possible to measure to tension force on the rope between the two objects. A motion sensor graphs the movement of the system and from the slope it is possible to calculate the acceleration of both

: As you can see that the greater the amount of pennies were added at the top of the cup‚ the shorter the distance of the cup moved and it included all of the three Newton’s laws. My hypothesis actually turned out to be accurate. It’s really fascinating that how only 1 experiment can prove all of Newton’s three laws of motion just like that. When the marble was getting released from the ramp I observed it hitting the cup and surprisingly the cup didn’t fall off or changed directions it went in

Review Sheet for Gas laws Name ___________________________ 1. A gas at 2.3 atm occupies 12 liters. The volume is changed to 6 liters what is the resulting pressure? 2. A sample of gas is confined to 30ml at a pressure of 6 atmospheres. When the pressure is changed to 3liters‚ what is the resulting pressure? 3. A gas occupies 30 L. When the gas is heated from 50C to 100C‚ what is the final volume? 4. In a lab‚ Neon vapor occupied a volume of 1 liter at STP‚ the volume was changed to 4 liter

Charles’ Law and estimate Absolute Zero In this IB Lab you will be assessed on the following criterion Conclusions and Evaluation Aim: Physics has many hundreds of laws and these can be tested in experiments to see if they are true. In 1787 the French scientist‚ J.A.C. Charles‚ published a law connecting the volume and temperature of gases. Your task is to see if you agree with his law. Another thing you have to consider is “ is my experiment accurate enough to prove or disprove the law ?“. It
