3) Given that an adult man who has fully exhaled during normal breathing has a thoracicvolume of 3.3 L at 1.0 atm. In preparation for inhalation, the man's diaphragm contractsto increases the thoracic volume to 3.8 L. Assuming that this volume change doesn'tresult in air inhalation, what is the new thoracic pressure? Show the calculation.
