Question

In order to determine an experimental value for absolute zero, a student submerged a flask containing a fixed amount of air into a beaker of water. By varying the temperature and measuring the corresponding pressure values for the trapped gas, she obtained the following data: Enter these data into Logger Pro (Pressure in X and Temperature in Y). Perform a linear regression, i.e., determine the equation of the straight line that best fits the data (see Graphing exercise, page 24) Record the slope and Intercept of the line of best fit: m (slope): b (intercept):= Record the goodness of fit parameters: Correlation= RMSE= From this regression analysis, what temperature corresponds to zero pressure (i.e., what temperature in degree C corresponds to absolute zero). Using the equation of the line, solve for the temperature of the trapped gas that corresponds to a pressure of 0.488 atm. using the equation of the line, solve for the pressure of the trapped gas when the temperature is lowered to -40.0 degree C.
