6. a large balloon containing 2.00×103 m3 of helium gas at 1.00 atm and a temperature 15.0◦ c rises rapidly from ground level to an altitude where the atmospheric pressure is only 0.900 atm. assume that the helium behaves as an ideal gas and that the balloon rises so rapidly that no heat is exchanged with the surrounding atmosphere. a. calculate the volume of the helium gas at the higher altitude. b. calculate the temperature of the gas at the higher altitude. c. what is the change in the internal energy of the helium as the balloon rises to the higher altitude?
