Derive a linear relationship between gas density and tem-perature, and use it to estimate the value of absolute zero temperature (in ^oC to the nearest 0.1^oC) from an air sample whose density is 1.2930 g/ L at 0.0^oC and 0.9460 g/ L at 100.0^oC. Assume air obeys the ideal gas law and that the pressure is held constant.
