A "normal" blood pressure has a gauge pressure of 120 millimeters of mercury [mm Hg] (systolic reading) over 80 millimeters of mercury [mm Hg] (diastolic reading). Determine the differential pressure, or the difference between the systolic and diastolic pressures, in units of atmospheres [atm].

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
