Some claim that mountain climbers suffer from headaches due notonly to a lack of oxygen in the brain, but also to the expansion ofthe brain in the cranium. Find the fractional change of the brain’svolume due to a reduction in pressure from 101 kPa at sea level to28.6 kPa high in the Himalayas. The bulk modulus is 2.10 GPa.(Another reason the brain expands is the dilation of the bloodvessels in the brain in order to deliver more oxygen.)
