Coffee is decaffeinated industrially using supercritical (sc) CO2. One advantage to using scCO2 is that the polarity of the supercritical fluid can be tuned by varying temperature, pressure and cosolvent additives.

The relationship between pressure and temperature of a gas, when volume and moles of a gas are held constant, is: P*T = k. TRUE FALSE
