A walker carried a balloon filled with 10 L of air, from sea level (where the atmospheric pressure was 101 kPa), up a mountain to a height of 3000 m (where the atmospheric pressure was 70 kPa). What would be the approximate volume of the balloon at 3000 m?

C: Boyle’s law states that volume must increase if pressure decreases, so choices A & B are wrong. If pressure decreases by 70/101, then volume must increase by 101/70 = 1.4. so 10 L × 1.4 = 14 L.
