External Pressure in Chemical Thermodynamics Formulas

External Pressure are always present when either the body forces are transmitted through support surfaces or, alternatively, when an orthosis applies correctional forces through soft tissues. And is denoted by P_ext. External Pressure is usually measured using the Pascal for Pressure. Note that the value of External Pressure is always negative.
