Describe the relationship between the pressure and the temperature of a confined gaseous sample. What equation is used to best describe this relationship (answer in DQ a)? Hint: There are two correct answers, but proceed with the one that lists in the numerator; DQ a) Use that equation and the values obtained from Step 13 of the Data Analysis to complete Table 2. a. Below, write the general equation describing the relationship between pressure and temperature: b. Below, write the specific equation (see the trendline) used to complete this part (with the exact values of m and b): Using the answer from DQ6a, calculate an average of the four values of from the table above. In this study, what are the appropriate units of ? Using the equation from Discussion Question and value of from Discussion Question calculate the expected pressure of the gaseous sample at a temperature of -50 °C. Calculate the pressure at a temperature of 200 °C. Calculate these two new pressures using a second method (DQb): the equation for the trendline on the Part B graph. What are the expected pressures at -50 °C and 200 °C using this method? Are they similar to the calculated pressures from Discussion Question 7? If not, describe one or more sources of error within the experiment that might account for any discrepancies.
