Question

Mark the correct advantage of Fortin’s barometer.
(A) it is portable
(B) it makes move accurate reading than simple barometer
(C) both
(D) none

Answer 1

Hint: The barometer is the device which is used to find the pressure of the air in the environment. There are many types of the barometers available and the different types of the barometers are having the different applications. The pressure in the different applications can be found by the different types of the barometers.

Complete answer:
The Fortin’s barometer is also one of the types of the barometer, and it is also used to find the air pressure in the atmosphere. In this type of the barometer, the mercury is the working fluid. In the Fortin’s barometer, the working fluid of mercury level is in the glass bottom of the barometer. And the level of the barometer is adjusted to the zero level in the scale of the barometer.
When allowed to pass inside the tube, the pressure of the air will lead to move the surface level of the mercury inside the tube. The level of the mercury inside the tube will change its position depending on the pressure of the air which is allowed to flow inside the tube. And the main advantage of the Fortin’s barometer is that it is very easy to transport, which means the position of the Fortin’s barometer is changed very easily. And also, it will give more accuracy.

Hence, the option (C) is the correct answer.

Note:
The construction of the Fortin’s barometer is simple so it is very easily portable. The height level of the mercury is directly proportional to the pressure of the air which enters the Fortin’s barometer. The barometer is used only to measure the air pressure.
