Gas Pressure and Volume Experiment, In this simple experiment, you will use a Gas Pressure Sensor and a gas syringe to study the relationship between gas pressure and volume. Temperature and amount of gas will be kept constant. The results will be expressed in words, in a table, with a graph, and with a mathematical equation., Use a Gas Pressure Sensor and a gas syringe to measure the pressure of an air sample at several different volumes., Make a table of the results., Graph the results., Predict the pressure at other volumes., Describe the relationship between gas pressure and volume with words and with a mathematical equation., computer, Vernier computer interface, Logger Pro, Vernier Gas Pressure Sensor with 20 mL gas syringe, Prepare the Gas Pressure Sensor and an air sample for data collection., Prepare the computer for data collection by opening the file '30 Pressure and Volume' from the Physical Science w Vernier folder., Collect the pressure vs. volume data., Record the pressure and volume data pairs displayed in the table., Examine the graph of pressure vs. volume., Print a copy of the graph., What happened to pressure when the volume was halved?, The pressure was doubled., What happened to the pressure when the volume was doubled?, The pressure was halved., What is the pressure when the volume is 16 mL?, The pressure when the volume is 16 mL is 62 kPa., What would the pressure be at 40.0 mL? At 2.5 mL?, At 40 mL, the pressure is 25 kPa and at 2.5 mL, the pressure is 380 kPa., The pressure of a gas is inversely proportional to its volume., P V = k
