Aweather balloon is designed to expand to a maximum radius of 21 m at its working altitude, where the air pressure is 0.030 atm and the temperature is 200 k. if the balloon is filled at atmospheric pressure and 323 k, what is its radius at liftoff?
Answers: 3
= Initial pressure = 0.03 atm
= Final pressure = 1 atm
= Inital radius = 21 m
= Intial volume of gas = 
= Final volume of gas = 
= Initial temperature = 200 K
= Final temperature = 323 K
