According to Boyle's law, the product of pressure and volume is a constant. Hence,
if volume of lungs is increased, the pressure decreases disproportionately
if volume of lungs is increased, the pressure remains the same
if volume of lungs is increased, the pressure decreases proportionately
if volume of lungs is increased, the pressure also increases proportionately
