Which of these is NOT equivalent to 1 atm of pressure?

Answer:

101.325 kPa

explaination:

1 atmosphere (atm) is a unit of pressure defined as being precisely equal to 101.325 kilopascals (kPa), 760 millimeters of mercury (mm Hg), or 760 torr. Therefore, while 720 torr and 760 mm Hg are equivalent to 1 atm, 101.325 kPa is simply the definition of 1 atm and does not represent a different value. Hence, the correct answer is 101.325 kPa, as it is not a different unit of measurement but rather the standard definition of 1 atm.
