Answer:
The correct answer is option D.
Explanation:
Barometer is device used to measure the atmospheric pressure.There are two types of barometer:
1. Mercury barometer :This barometer measures the atmospheric pressure by adjusting the height of mercury inside the tube.
2. Aneroid barometer This barometer measures the pressure by the expansion of metal which is an alloy of beryllium and copper.
A difference between a mercury barometer and an aneroid barometer is The aneroid barometer does not use mercury to measure pressure changes.
A barometer is an instrument used to measure the air pressure of a certain environment.
It tracks atmospheric pressure fluctuations caused by the migration of warm and cold weather systems to predict the weather using liquid mercury.
The more accurate millibar (mb), equivalent to exactly 100,000 Pa, is most commonly used by meteorologists to describe pressure.
Thus, the correct option is D, The aneroid barometer does not use mercury to measure pressure changes.
