Lab Report Experiment 4
Introduction
In this experiment we measured the relationship between temperature, volume, and pressure.
Objectives:
Conduct a set of experiments, each of which illustrates a gas law.
Gather data to identify the gas law described by each activity.
Complete the calculations necessary to evaluate the gas law in each activity.
From your results, derive a single mathematical relationship that relates pressure, volume, and temperature.
Hypothesis: As the temperature increases the pressure increases and if temperature decreases the pressure decreases. Also as the volume increases the pressure will decrease and if the volume increases the pressure will decrease.
Experimental Procedure
Part 1:
First we connect the LabQuest to the gas pressure sensor and choose New from the file menu. Then we set up the data collection mode to events with entry and change the name to Volume and units to mL. After setting up both gas pressure sensor and LabQuest we grab the 20mL syringe and set it up to 5, then you connect it to the gas pressure sensor and make a half twist to lock it. After that the pressure will appear in the LabQuest. Gather the data and continue to the next volume measurement to gather the pressure data.
Part 2:
First we need to change the data collection to events with entry and change the name to Volume and the units to mL. After that connect the temperature probe to the LabQuest and select new from the file menu. Now that you have the LabQuest ready you need to assemble the Erlenmeyer flask with the rubber stopper (make sure it’s tight). Now set up large containers of water baths from ice water to hot. Use a large volumetric beaker so that way the Erlenmeyer flask fit inside. After that change the graph settings to display graph of pressure vs. temperature. Now you can start collecting you data from the different temperatures.
