The aneroid barometer is a device for measuring atmospheric pressure. Type 1 for true and 0 for false.

Hint: The device used to measure atmospheric pressure is called barometer. There are mainly two types of barometers and they are mercury barometer and aneroid barometer. Mercury barometer is a liquid barometer whereas aneroid barometer is a non-liquid barometer.

Complete step-by-step answer:
The device used to measure atmospheric pressure is called a barometer. The common use of a barometer is to check the rise or fall in the pressure of the atmosphere. This is how weather conditions are predicted. Barometer also helps in understanding the nature of storms.
There are mainly two types of barometers – mercury barometer and aneroid barometer.
A classical or mercury barometer consists of a glass tube with one end sealed and other end open. This tube is filled with mercury and placed upside down in a bigger container called a reservoir. Even the reservoir contains mercury. When the tube is placed inside the reservoir, due to pressure difference the mercury level in the glass tube decreases creating vacuum at the top of the tube.
We know to calculate the pressure in a mercury column. If we know the pressure of mercury at a certain level, it will be the same at any other point on this level. The pressure of air just above the reservoir is equal to the pressure in the mercury column at the same level.
Aneroid barometer does not contain any fluid in it. It has a flexible metal box made up of an alloy of beryllium and copper. This metal box is called an aneroid capsule. As the atmospheric pressure changes the dimensions of the metal box changes. This means that the box may expand or contract based on the change in the atmospheric pressure. With this the atmospheric pressure is measured.
Therefore, the given statement is true.
Hence, the correct answer is 1.

Note: Both the mercury barometer and the aneroid barometer work on the same principle of expansion and contraction. However, the mercury barometer is relatively simple and accurate. Aneroid barometer needs a complex mechanism.
