Question

A barometer accelerating downwards reads 76cm of Mercury. What will be the possible air pressure inside the gas?​

Answer 1

Answer ⇒ Air Pressure Inside the gas is 1 atm or 1.01 × 10⁵ Pa.

Explanation ⇒

Given conditions,

Height of the Mercury Column(h) = 76 cm.

Using the formula,

  Pressure = height of the column × density of the mercury × acceleration due to gravity.

We know, that, density of mercury = 13600 kg/m³

Acceleration due to gravity = 9.8 m/s².

Substituting these values in the Formula, we will get,

 

  Pressure = 76/100 × 13600 × 9.8

∴ Pressure = 76 × 136 × 9.8

∴ Pressure = 101292.8

∴ Pressure = 1.01 × 10⁵ Pa.

OR Pressure = 1 atm.  [Since, 1 atm = 1.01 × 10⁵ Pa.]

Hence, Air Pressure Inside the gas is 1 atm or 1.01 × 10⁵ Pa.
