PPT-Real gasses For an ideal gas, the compressibility factor Z = PV/nRT is equal to unity

1 Lets see what the van der Waals equation of state predicts Or We can expand the first term on the righthandside as so the van der Waals prediction is Depending on the temperature and on the value of a and b the correction to Z can be both positive or negative exactly as we see in the figure .

The atmosphere is important for life on earth. Provides . a medium for many chemical reactions with waste products. Courtney. Good Thing/ Bad Thing. Traps heat so that it doesn’t get lost in space. Keeps oxygen in our atmosphere. Greenhouse gasses absorb infrared radiation (protects us from getting burnt up by the radiation from the sun). P. V. . =. . n. R. T. P. . = pressure in . atm.

Dalton’s Law of partial pressure states that the total pressure exerted by a mixture of gasses is the sum of the pressures exerted independently by each gas in a mixture.
