At a certain instant the volume is 75 cubic inches, thepressure is 30 psi, and the pressure is decreasing at the rate of 2 psi every minute. What is therate of change of the volume at that instant?1.6. Using dimensional analysis, convert 4.3 x 10-5 atmospheres to its corresponding CGS unit.High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purity chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the pressure in torr.
