Solution

The correct option is C very high speed of wind after some time
When it rises, it often means clear weather. When the air is warm and wet, the barometer reading falls. When the air pressure falls, it usually indicates some type of storm or wet weather is coming. If the barometer remains steady, there will be no immediate change in the weather.

A faulty barometer contains certain amount of air and saturated water vapour. It reads 74.0 cm when the atmospheric pressure is 76.0 cm of mercury and reads 72.10 cm when the atmospheric pressure is 74.0 cm of mercury. Saturation vapour pressure at the air temperature = 1.0 cm of mercury. Find the length of the barometer tube above the mercury level in the reservoir.
