An airplane passenger has a volume V1 of air in his stomach just before the plane takes off from a sea-level airport. What volume will this quantity of air have at cruising altitude at the same temprerature ( body temp. ), in terms of V1, the pressure on the ground P1, and the cabin pressure at cruising altitude P2? What is this volume, in cubic centimeters, if the initial volume is 110 cm^3 and the cabin pressure drops to 7.5x10^4 Pa when the plane is at cruising altitude?
