i) Manometer
ii) Barometer​

Answer 1

Answer:

Barometer, device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. There are two main types of barometers: mercury and aneroid.

A manometer can be designed to directly measure absolute pressure. The manometer in Figure 5 measures the pressure compared to zero absolute pressure in a sealed leg above a mercury column. The most common form of this manometer is the conventional mercury barometer used to measure atmospheric pressure.
