NTRODUCTION In this experiment the validity of Gas Laws were observed and the relationship of two variables, temperature and volume, against pressure was tested. Gas Laws are encompassed by the Ideal Gas Law in which PV=nRT observes the general behavior of a gas under ideal conditions in terms of pressure(P), volume(V), moles of gas(n), gas constant(R), and temperature(T). The Ideal Gas Law is a combination of Boyle 's Law, Charles ' Law and Avogadro 's Law and was first introduced in 1834 by Emile Clapeyron. For the purposes of this experiment, attention is given to Boyle 's Law and Guy-Lussac 's Law. British scientist Robert Boyle discovered the relationship between volume and pressure by using a J-tube and observing the volume that the gas occupied decreased as more mercury and thus pressure was exerted into the tube. His theory that the volume occupied by the gas acts inversely to the pressure exerted upon it can be expressed mathematically as PV=K. The pressure of a gas of fixed mass and fixed volume is directly proportional to the gas 's absolute temperature, this physical law was formulated by the French chemist and physicist Gay-Lussac in 1802.² Joseph Louis Gay-Lussac expanded upon the work of Jacques Charles and is accredited to the equation (P/T)=K however, to a lesser known extent it is also due to the work of Guillaume Amontons that this relationship was discovered using an “air thermometer”. Calculations were done using the volume, pressure, and temperature…
