In New york you had a balloon inflated with helium (He) and you measured its temperature, which was 89.6 degree F, and its pressure, which was 100,000 N/m^2. In Colorado, however, you noticed that the temperature of the He was 69.8 degree F and the pressure was 90,000 N/m^2. (a)Calculate the compressibility factor of He in the two cities. (b) calculate the ratio of He volume in Colorado over that in New york.
