Graphs are often used to deliver a visual and compelling case in many applications and businesses. Graphs are the information delivery vehicle of choice for many numerical data applications. With graphs a lot of information can be condensed into a visually descriptive object. They reduce the amount of time that would have been expended in reading or parsing through a lot of information. On the other hand‚ they can also be easily used to misrepresent or skew interpretation towards a favorable

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:

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

Born in Cork‚ Ireland‚ in the year 1627‚ Robert Boyle was born into a very rich family. His father‚ Richard Boyle‚ was the Earl of Cork. Part of Boyle’s success was because he lived with one of the richest men of Ireland. Richard Boyle‚ however‚ gained his money through stealing. His mother died before he was 12. Though he did well at his school initially‚ when a new headmaster arrived‚ Boyle did poorly. His father removed him from his school‚ and hired a tutor to teach him

verify Snell’s Law and find the relationship between angle of incidence and the angle of refraction‚ for monochromatic light passing from air into Perspex. Hypothesis: As the angle of incidence increases so will the angle of refraction (directly proportional). Apparatus: * Laser (Monochromatic light) * Rectangular Perspex * Ruler * Pencil * Paper * Protractor * Calculator Method: 1. Place your Perspex in the middle of a piece of paper. 2. Use a sharp pencil

Robert Boyle employed a J-shaped piece of glass tubing that was sealed on one end. A gas (air) was trapped in the sealed end of the tube and varying amounts of mercury were added to the J-shaped tube to vary the pressure of the system. Boyle systematically varied the pressure and measured the volume of the gas. These measurements were performed using a fixed amount of gas and a constant temperature. In this way Boyle was able to examine the pressure-volume relationship without complications from
