Stress may trigger some headaches. This could be related to increased (hypertension) or decreased (hypotension) osmotic pressure in cerebrospinal fluid and inside the skull. The human body temperature also may be influenced by these changes. Calculate the pressure p ( in units of torr) inside the brain, if it resulted in 39oC fever. You need to assume a normal body temperature is 37oC, the average CP,m of the human body is approximated as 12.5R, and the outside pressure is 1 atm. Also, assume the process of giving the headache is adiabatic.

Underwater, the pressure increases by 1 bar for every 10 m of depth. When a scuba diver breathes pressurized air in which the partial pressure of N2(g) exceeds 4 bar, the result is nitrogen narcosis, which is similar to alcohol intoxication. What is the maximum mole percent of N2 in an air mixture that could be used by divers at depths up to 85 m below sea level without undue risk of nitrogen narcosis?

A parcel of unsaturated air contains a mixture of dry air and water vapor. The specific humidity q of the air parcel is 12 g kg^−1. Recall that q = Mv / (Mv+Md),where Mv is the mass of the water vapor and Md is the mass of the dry air. This is equivalent to what we have been calling the fractional concentration of water vapor by mass. (a) If the air parcel is at a temperature T= 25◦C , what is the virtual temperature of the air parcel? (b) If the air parcel is at a temperature T= 25◦C and a pressure of 1000 hPa, what is the relative humidity of the air parcel? (c) What is the apparent molar mass of the air parcel?
