Open Question
How many times larger is carbon dioxide’s contribution to the greenhouse effect compared to methane? (Use radiative forcing values in Table 10.7 to compare the two gases.)
Pakistan's K2 is the world's second-tallest mountain, with an altitude of 28,251 ft. Its base camp, where climbers stop to acclimate, is located about 16,400 ft above sea level. (a) Approximate atmospheric pressure P at different altitudes is given by the equation P = e-h/7000, where P is in atmospheres and h is the altitude in meters. What is the approximate atmospheric pressure in mm Hg at K2 base camp?
