Question:
The vacuum in a closed container is 50 mm of Hg The absolute pressure in the container is
The vacuum in a closed container is 50 mm of Hg The absolute pressure in the container is
Show Hint
Remember that absolute pressure is the atmospheric pressure minus the vacuum pressure and convert the vacuum pressure from mm of Hg to bar

- 0.92 bar
- 0.90 bar
- 0.95 bar
- 0.82 bar

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The atmospheric pressure is \( 1 \, \text{bar} \), and the vacuum pressure is \( 50 \, \text{mm of Hg} \). The absolute pressure is calculated as:
Absolute pressure = Atmospheric pressure – Vacuum pressure
\( = 1 \, \text{bar} - \frac{50 \, \text{mm of Hg}}{760 \, \text{mm of Hg}} \times 1 \, \text{bar} = 0.92 \, \text{bar}. \)
