You have a perfect gas that undergoes thermal compression (constant temperature) which reduces its volume by 2.50 dm³. The final pressure and volume are 2.01 bar and 1.98 dm³, respectively. Calculate the original pressure in torr.
The ideal gas law is a limiting law, in that it is expected to hold as pressure approaches zero. Suppose the following measured values have been obtained for oxygen gas at 273.15K. Based on the data, calculate R for each pressure value and create a table of pressure and R values (i.e. you are treating R as a variable rather than a constant at this point). Then create a plot R vs p and find the “best value” of R by determining the y-intercept of a straight line fit. (Be sure to label your axes including units).
