Boyle’s law may be stated as: “when the volume of an enclosed gas expands, its pressure decreases”. Thus the pressure in our lungs will: A. increase as our diaphragm contracts. B. be negative as we breathe out. C. be negative as our rib cage moves up and out. D. be positive as our rib cage moves up and out
