Question

What is an altimeter? How is a barometer used as an altimeter?

Answer 1

1. Altimeter is a device that is used to measure the altitude of any place based on the atmospheric pressure at that point.
2. As the altitude (height) increases, the atmospheric pressure decreases.
3. Based on this principle, we can determine the altitude of any place if we measure the atmospheric pressure at that place.
4. An altimeter consists of a barometer that is calibrated to show the altitude reading corresponding to the value of atmospheric pressure at that point.
