Question

QUESTIONS #10 #16 REFER TO THE FOLLOWING DATA: A study was made of the effect of temperature on the volume of 10.00 g of nitrogen (N2) gas, with the pressure held constant at 1 atm. The data for this experiment were: T, °C 20.0 V, L 8.59 40.0 9.18 60.0 9.76 80.0 100.0 10.34 10.93 10. (0.5 pt) Which property is the dependent variable? 11. (1pt) Plot the above data using Excel. On your plot, show the equation of the plot and the R-value. Use the plot to Answer Questions 12-16. 12. (1pt) Is there a linear relationship between the volume and the temperature of N2 at constant pressure at latm? 13. (2 pts)At what volume would the N2 sample have a temperature of 70 °C? 14. (2pts)At what temperature would the N2 sample have a volume of 9.0 L?

Answer 1

For your data, the regression equation for Yis: y = 0.0292X+ 8.008 As you can see the output from this calculator is fairly verbose. Mostly it should be self-explanatory, but you should note that any apparent discrepancies in calculations are because rounding is used for the purposes of display, but not for the calculations themselves. If you wish to perform a further calculation, it is necessary to hit the reset button at the bottom of the page.
