Aprocess depressurizes nitrogen adiabatically from an unknown pressure to 1 bar. the temperature of nitrogen is initially 300 k and after depressurizing it is 200 k. assuming nitrogen is an ideal gas, and that gas heat capacity of nitrogen is given by: cigp=31.1−0.0135t+2.68×10^−5t^2−1.1 7×10^−8t^3jmol^−1k^−1 a) calculate the initial pressure of nitrogen. b) calculate the entropy change of nitrogen due to this process.

Is the time in tennessee the same as florida Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
