Atmospheric pressure at sea level is about:
A1 Pa in standard practice
B1 atm or about 101325 Pa
C100 Pa
D10 atm
Answer & Solution
Correct answer: A. 1 Pa in standard practice
1. At sea level the air column above us exerts pressure.
2. Standard atmospheric pressure is 101325 Pa.
3. This is also written as 1 atm.
4. So 1 atm equals about 101325 Pascal.
