a. a balloon is filled at sea level on a spring day (temperature 200c) to a volume of 0.500 m3 and then brought atop of mount everest the same day (temperature -200c). how does its volume change? what is the percent change?
b. what is the air density atop of mount everest on a summer day (at a pressure of 3.30 x 104 n/m2 and a temperature of -190c)? how is it different from the density of air in standard conditions (at a pressure of 1.01 x 105n/m2 and a temperature of 200 c the air density is1.28 kg/m3). the molar mass of air is 28.8 g/mole.
