Introduction The purpose of this lab is to test the relationship between Pressure and Volume which is known as Boyles Law. We are testing Boyles law by using a compression chamber that can be sealed to create a closed system. While conducting the experiment, we are asked to create a closed system by closing the relief valve and very slowly opening the needle valve to allow the flow of the oil into the chamber. We kept the flow of the liquid into the chamber at a very slow rate to allow for no change in temperature so that it remains constant. While holding the temperature constant, the change in the internal energy will become constant by assuming that air is behaving as an ideal gas throughout the entire experiment. While the oil is entering the chamber, we are asked to record the value of pressure inside of the chamber with the change in volume. The gathered data will be used to create graphs to help draw conclusions about Boyles Law. The other purpose of this lab is to test the relationship between Pressure and Temperature which is known as Gay-Lussac Law. We are testing this law by using a heat chamber to prove that if volume is held constant, that when temperature is increased inside of a closed chamber, that the pressure will also increase. While the temperature increases inside of the chamber, we are asked to measure the pressure inside of the chamber at different temperatures. Once the experiment is complete, we will use the data collected to create graphs to help us draw conclusions about the Gay-Lussac Law.

Method In the first part of this lab, we used an apparatus that allowed us to create an open and a closed system using the air discharge value located at the top of the chamber. This chamber is also equipped with volume, temperature and pressure indicators to help us conduct the experiment by displaying the data that we need to record. In the second part of this lab, we used an apparatus that allowed us to also create an open or a closed system using the air discharge valve which is located at the top of the chamber. This chamber is equipped with a temperature indicator and a pressure indicator to help us conduct the experiment by displaying the data that we need to record.

Results Isothermal Compression Data: The table below shows the data recorded during this experiment where we are testing Boyles Law. From the data below we see that the pressure and volume have a inverse linear relationship with each other. When temperature is held constant, we are able to observe that the pressure is inversely proportional to volume.

Isochoric Heating Data The figure below shows data that was recorded during this experiment where we are asked to test the relationship between Temperature and Pressure, known as the Gay-Lussac Law. From the data below, we are able to see that the relationship between pressure and temperature is directly proportional to each other. As we keep the volume constant, we see that as the temperature is increased, the pressure also increases proportionally to the temperature increase.

Conclusion After performing this experiment and creating graphs from the data that we collected, we are able to make some clear observations. During the first part of the experiment, we are able to observe that as the volume of air inside of the chamber decreased, the pressure inside of the chamber begins to increase. During this part of the experiment we were able to also confirm that the temperature remained constant during the entire experiment. During the second part of the experiment, we are able to observe that as the temperature increases inside of the chamber, the pressure also begins to increase with respect to the change in temperature. Both parts of this experiment helps us understand the concepts that are behind the ideal gas law.
