Atmospheric pressure at sea level in pascal is approximately
A. 1.01 × 10⁷ Pa
B. 1.01 × 10⁹ Pa
C. 1.01 × 10³ Pa
D. 1.01 × 10⁵ Pa
Answer: Option D
Solution (By JKExamLibrary)
Standard atmospheric pressure 1 atm = 1.01325 × 10⁵ Pa ≈ 1.01 × 10⁵ Pa = 101 kPa. Also equals 760 mm of Hg. This is an important conversion for pressure units.
