During inhalation, a person's diaphragm and intercostal muscles contract, expanding the chest cavity and lowering the internal air pressure
below ambient so that air flows in through the mouth and nose to the lungs. Suppose a person's lungs hold 1300 mL of air at a pressure of
1.00 atm. If they expand their chest cavity by 460 mL while keeping their nose and mouth closed so that no air is inhaled, what will be the air
pressure in their lungs in atm? Assume the air temperature remains constant.

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
