Expert Answer
Aneroid barometers helps to measure the atmospheric pressure. Aneroid barometer has aneroid cell which is made of alloy of beryllium and copper. This alloy under goes expansion and contraction on the change in pressure. Thus, the mechanical levers of aneroid cell expand and contract and display the reading on the aneroid barometer by the movement of the pointer.
