Argon is a chemical element with atomic number 18 and a noble gas. A study of the volume of argon at different pressures gave the following data: P (atm) 0.500 0.600 0.700 0.800 0.900 1.00 1.10 1.20 1.30 1.40 1.50 VAR (L) 44.7 37.5 32.0 28.1 24.7 22.6 20.4 a. (6 points) Plot the volume versus pressure and label your graph properly. Add a curve fit (inverse equation). Include this graph in your lab report. Equation: Slope: 18.9 17.0 16.2 15.0 b. (2 points) Using a trendline to estimate the value for a variable within the range of a data set is called interpolation, while estimating a variable outside the range of a data set is called extrapolation. The Interpolate tool in Logger Pro can be used to do both. Determine the volume of argon at a pressure of 0.850 atm by interpolation. Note you may need to zoom in or out or change the scale. y-intercept: Correlation: c. (2 points) Determine the volume of argon at a pressure of 0.300 atm by extrapolation. d. (10 points) As shown in the Logger Pro tutorial, add a calculated column with 1/P values and plot V vs. 1/P. Add a linear trendline and write down the details for the trendline. Include this graph in your lab report. Argon is a chemical element with atomic number 18 and a noble gas.
