A plastic bag is filled with hydrogen at atmospheric pressure and 23.0 oC. Assume that the mass of the bag is negligible and take the temperature of the outside air to be 0 oC. With the help of this "balloon" we want to lift a 60.0 kg girl off her feet. If hot air is used instead of hydrogen, what is the required volume of the balloon if the air inside can be maintained at 43.0 oC ?
