Question

In Barometer , the weight of the column in the tube is equal to the force applied on it by the mercury in the bowl due to atmospheric pressure.

• A. True
• B. False

Answer 1

The correct option is A True

Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. The weight of the column in the tube is equal to the force applied on it by the mercury in the bowl due to atmospheric pressure.
