A balloon partially filled with helium has a volume of 30 m3 30 \mathrm{~m}^{3} at the earth's surface where pressure is 76 cm Hg and temperature is 27∘C 27^{\circ} \mathrm{C} . What will be the increase in volume of gas if balloon rises to a height, where pressure is 7.6 cm Hg and temperature is −54∘C -54^{\circ} \mathrm{C} ?
