Q.  Which of the following is the correct equivalent of 1 atmosphere?

a. 1 atmosphere = 1.013 × 10⁵Pa
b. 1 atmosphere = 1.013 × 10⁴Pa
c. 1 atmosphere = 1.013 × 10³Pa
d. 1 atmosphere = 1.013 × 10²Pa


ANSWER: See Answer
 
A common unit of pressure is the atmosphere (atm), i.e. the pressure exerted by the atmosphere at sea level (1 atm = 1.013 × 10⁵Pa).
