Gas Law Lab Report

The task of this lab is to create and analyze hypotheses of the different relationships between the properties of gasses. These properties include temperature, pressure and volume. The ideal gas law is the source for many of these hypotheses and are tested through the various known laws of gasses. Such laws include Lusaacs Law, Charles Law and Boyles Law. The data, gathered from the results of the experiments mentioned above, was then graphed to show the relationship between the properties that gasses inhibit. The data provided was also utilized to derive a proportionality constant, k. Pressure rises when temperature rises, pressure rises when volume falls and volume rises when temperature rises. All of these outcomes were observed during the

Boyle’s Law includes holding the temperature constant while analyzing the correlation between volume and pressure. An electronic tool was used in this trial called a LabQuest. As the volume of water is manually reduced, the LabQuest measures the pressure of the closed system while temperature is held constant. While analyzing the data and reading the measurements it was concluded that when volume is decreased, pressure will increase and as volume is increased, pressure will decrease. This was concluded because all the other properties in the ideal gas law were constant. The second trial conducted dealt with Gay-Lusaac’s Law. Gay-Lusaac’s Law includes holding the volume constant while looking at the relationship between pressure and temperature. A flask was immersed into an ice bath and the pressure was recorded. The temperature of this ice bath was then raised and the pressure was measured each time the temperatures of the ice bath was raised. Pressure and temperature are inversely proportional, meaning as temperature goes up and the pressure does also. The same happens when the temperature is decreased. When temperature is decreased the pressure also

A pressure sensor was sealed inside a closed Erlenmeyer flask. That flask was then immersed into an ice bath where a temperature sensor is also immersed. The ice bath was set to 0 degrees Celsius or 273 Kelvin. The starting measurements were again observed and documented in the lab manual. Hot water was added to the bath until the bath rose 10 Kelvin in temperature. The pressure was recorded when it stabilized. This processes was repeated three more times until the four measurements spanned a temperature range of 40-50 K. LoggerPro was used to graph the data
