A balloon, considered spherical, is 30 ft in diameter. The surrounding air is at 81 °F and the barometer reads 30.65 in Hg. What gross load may the balloon lift if it is filled with a) hydrogen at 112 °F and atmospheric pressure. b) helium at 112 °F and atmospheric pressure? C)Helium is nearly twice as heavy as hydrogen. Does it have half the lifting force of hydrogen?
