Column of manometer which faces liquid is __________ ?
Correct answer: B. Depressed
- A. Raised
- B. Depressed
- C. Compressed
- D. Remains same
Explanation
In a manometer, the liquid column on the side exposed to greater pressure is pushed down, so that column is depressed. A student may select “raised” by following the movement of the opposite arm, which rises as the high-pressure side falls.

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
