1) A balloon filled with helium gas has a volume of 744 mL at a pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm. Assuming that the temperature has remained the same, what volume does the gas occupy at this height? Answer in units of mL. 2) A lungful of air (337 cm3 ) is exhaled into a machine that measures lung capacity. If the air is exhaled from the lungs at a pressure of 1.88 atm at 42.1 ◦C but the machine is at ambient conditions of 0.958 atm and 23 ◦C, what is the volume of air measured by the machine? Answer in units of cm3 .
