MODEL 3: PARTIAL PRESSURE Dry air is 78% nitrogen, 21% oxygen, and 1% argon. A percentage is a ratio: "78%" means that out of 100 particles 78 will be nitrogen, or 0.78 as a fraction. Such fractions are unitless. CRITICAL THINKING QUESTIONS 15. Approximately what is the pressure in the room where you are working? (Include the units.) 16. What three gases are causing this total pressure? 17. What fraction (not percent) of air molecules are nitrogen molecules? Oxygen molecules?...

3. Most of the atmosphere is made of nitrogen and oxygen. At room temperature, the speed (velocity) of the molecules of N2 and O2 are plotted (horizontal) versus the abundance (amount) of molecules moving at that speed. Identify which gas is represented by which curve (or if both gases would be represented by the same curve), and justify your answer with a brief explanation. (4) venue each element nos Molecular spoed nometer.
