A helium balloon rises from the ground where the temperature and pressure are 23 °C and 1.0 atm. When the balloon reaches a height of 1 km, the temperature and pressure have both decreased to 13 °C and 0.90 atm. Assuming that the helium behaves as an ideal gas, predict the volume of the balloon at 1 km if its initial volume was 2.1 L. any heplp would be appreciated.
