Problem

A balloon partially filled with helium has a volume of

30\,\text{m}^3

at the Earth's surface, where the pressure is

76\,\text{cm Hg}

and the temperature is

27^\circ\text{C}

. What will be the increase in volume of the gas if the balloon rises to a height where the pressure is

7.6\,\text{cm Hg}

and the temperature is

-54^\circ\text{C}
