Experiment 7 PROCESSING THE DATA 1. In order to perform this experiment, what two experimental factors were kept constant? 2. Based on the data and graph that you obtained for this experiment, express in words the relationship between gas pressure and temperature. 3. Explain this relationship using the concepts of molecular velocity and collisions of molecules. 4. Write an equation to express the relationship between pressure and temperature (K). Use the symbols P.7, and k. 5. One way to determine if a relationship is inverse or direct is to find a proportionality constant, k, from the data. If this relationship is direct, k = P/T. If it is inverse, k - P.T. Based on your answer to Question 4, choose one of these formulas and calculate k for the four ordered pairs in your data table (divide or multiply the P and T values). Show the answer in the fourth column of the Data and Calculations table. How "constant" were your values? 6. According to this experiment, what should happen to the pressure of a gas if the Kelvin temperature is doubled? Check this assumption by finding the pressure at -73°C (200 K) and at 127°C (400 K) on your graph of pressure versus temperature. How do these two pressure values compare? DATA AND CALCULATIONS Ev.
