How large a volume of nitrogen is required

Reference no: EM13315665

A plastic bag is filled with nitrogen at atmospheric pressure and 27.0 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.

How large a volume of nitrogen (in m3) is required? If hot air is used instead of nitrogen, what is the required volume of the balloon if the air inside can be maintained at 39.0 oC ?
