Solution

The correct option is A True
Atmospheric pressure 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 to it by the mercury bowl due to atmospheric pressure.

Q. What will be the length of the mercury column in a barometer tube, when the atmospheric pressure is

Q. A barometer is constructed with its tube having radius 1.0 mm. Assume that the surface of mercury in the tube is spherical in shape. If the atmospheric pressure is equal to 76 cm of mercury, what will be the height raised in the barometer tube? The contact angle of mercury with glass = 135° and surface tension of mercury = 0.465 N m⁻¹. Density of mercury = 13600 kg m⁻³.

A barometer correctly reads the atmospheric pressure as 76 cm of mercury. Water droplets are slowly introduced into the barometer tube by a dropper. The height of the mercury column first decreases and then becomes constant. If the saturation vapour pressure at the atmospheric temperature is 0.80 cm of mercury, find the height of the mercury column when it reaches its minimum value.
