A pressure of 1 ~mm of mercury is equivalent to

Options

  1. A1 mPa
  2. B13.33 ~Pa
  3. C133.3 ~Pa
  4. D133.3 ~Pa

Correct answer

C. 133.3 ~Pa

Step-by-step solution

Height of mercury column h=1 ~mm =10⁻³ ~m Density of mercury, =13.6 10^3 ~kg ~m ⁻³ g=9.8 ~ms ⁻² Pressure, p= g h aligned & =13.6 10^3 9.8 10⁻³ & =133.28 ~Pa 133.3 ~Pa aligned
