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.

Kinetic-Theory of Gases

Kinetic theory of gases is the model or method which was developed in the 19th century by Maxwell and Boltzmann. This is possible as the interatomic force which is of short-range forces that are important for solids and liquids can be neglected for gases. This theory or gas law gives a molecular interpretation of the pressure and temperature of a gas and is consistent with gas laws and Avogadro’s hypothesis. This theory is very helpful to correctly explain the specific heat capacities of many gases, kinetic energy and it also explains the transport qualities such as viscosity, thermal conductivity, and diffusion with molecular parameters. As stated in the kinetic-molecular theory, the temperature of a substance or gas particle is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles, called average kinetic energy.
