large helium-filled balloons are used to lift scientific equipment to high altitudes.
(a) what is the pressure inside such a balloon (in atm) if it starts out at sea level with a temperature of 20.8°C and rises to an altitude where its volume is 22 times the original volume and its temperature is -35.7°C? (enter your answer to at least 3 decimal places)
(b) what is the gauge pressure? (enter your answer in atm and to at least 3 decimal places. assume atmospheric pressure is constant)
