Q: 1 atmosphere = ?
  • A. 1.01x10⁵Pa
  • B. 10.1x 10⁵ Pa
  • C. 1.01 x10⁶Pa
  • D. 10.1x10⁶Pa
Correct Answer: Option A - 1 Atmosphere = 101325 Pa = 1.01325 x 105 Pa ∵ 1 Bar = 1 x 105 Pa 1 Atmosphere = 1.01325 bar = 1 atmosphere = 101.325 kPa 1 atmosphere = 760 Torr 1 Atmosphere = 760 mm Hg column.
A. 1 Atmosphere = 101325 Pa = 1.01325 x 105 Pa ∵ 1 Bar = 1 x 105 Pa 1 Atmosphere = 1.01325 bar = 1 atmosphere = 101.325 kPa 1 atmosphere = 760 Torr 1 Atmosphere = 760 mm Hg column.

Explanations:

1 Atmosphere = 101325 Pa = 1.01325 x 105 Pa ∵ 1 Bar = 1 x 105 Pa 1 Atmosphere = 1.01325 bar = 1 atmosphere = 101.325 kPa 1 atmosphere = 760 Torr 1 Atmosphere = 760 mm Hg column.
