A weather balloon is filled with 115.0L of He and launched from sea level (T-20.0°C, P-755 torr). The balloon is designed to continue its ascent to an altitude of 30.0 km where it bursts, releasing a package of meteorological instruments that parachute back to Earth. 1st attempt Feedback See Periodic Table See Hint If the atmospheric pressure at 30.0 km is 28.0 torr and the temperature is -38.0 °C, what is the volume of the balloon when it bursts? 8913
