LabQuest. Once all the data was collected, we were able to determine the relationship of temperature and pressure by putting the data in a graph format in the LabQuest. Date and Calculations: Pressure (kPa) Temperature (ºC) Temperature (K) Constant, k 93.22 kPa 2.4ºC 275.4 K 0.338 93.39 kPa 26.7ºC 299.7 K 0.312 93.54 kPa 36.5ºC 309.5 K 0.302 93.70 kPa 93.6ºC 366.6 K 1.001 **Calculations are shown on page 36 of my attached lab notebook pages.
D. Claim Temperature and pressure have a direct relationship. For example, if temperature goes up, pressure goes up. E. Evidence After using the temperature probe and pressure gas sensor, we were able to determine the constant, k, by using the equation P/T, for each beaker. The values of all the pressures and temperatures were formatted in the LabQuest to form a graph, and the outcome of our graph (which is attached) showed a direct relationship between temperature and pressure. F. Reflection and Conclusion Our experimental results lead us to have an equation of y = -0.14+106.54. The higher the temperature, the higher the pressure and vise versa. If pressure goes up, the temperature will also go up. The only problems we really had were using the LabQuest. Even though there were instructions in the lab manual, it was still difficult to be able to do everything we needed to do.
