Aweather balloon is filled to a volume of 6000 l while it is on the ground, at a pressure of 1 atm and a temperature
of 273 k. the balloon is then released into the atmosphere. as the balloon rises, the pressure decreases to 0.3 atm
and the temperature decreases to 240 k. what is the final volume of the balloon at this temperature and pressure?
