Question
(4) In problem 1 above, you found that the temperature decreases linearly with height at a lapse rate given by . Use your equation for the temperature as a function of height to derive expressions for the variation of pressure, p(z), and molecular concentration, n (z) with height in a more typical atmosphere. (5) (a) Using your solution for (4) above, derive an equation for the total number (N) of molecules in a column of atmosphere with an area, A. (Hint: Be careful here You cannot integrate to infinity; think carefully about what your upper integration limit needs to be.) Does your solution have similarities to the equation for N that we derived in class? (b) Derive an equation for the average depth of the atmosphere, assuming that the atmospheric lapse rate is dry adiabatic. Does your solution have similarities to the equation you derived for the isothermal atmosphere in (3)?Explanation / Answer
ANSWER:
C is the molar concentration in mol/L (Molar or M). This is also referred to as molarity, which is the most common method of expressing the concentration of a solute in a solution. Molarity is defined as the number of moles of solute dissolved per liter of solution (mol/L = M).
