⚪State the disadvantages of using water as a barometric liquid⚪
✨

Answer 1

The use of water in a barometer has the following disadvantages :

1) The density of water is low , so nearly 10.4 m height of water column is needed to balance the normal atmospheric pressure. It will be highly inconvenient to take a tube of 10.4 m for a barometer.

2) The vapour pressure of water is high, so the vapours in the vacuum space shall make the reading inaccurate.

3) Water sticks with the glass tube and wets it,. so the reading becomes inaccurate.

4) Water being transparent, so its surface is not easily seen while taking the observation. 

Answer 2

Hey Mate..!!

Here's Your Answer..!!

Disadvantages of Using Water as Barometric Liquid-

✨Water gets stuck on the walls of the barometer. Therefore, providing inaccurate reading.

✨Water has a low density. This is the reason why a 10.4 m height of water column is required to balance the atmospheric pressure.
A tube this long is really inconvenient.

✨Water is transparent. Therefore, it cannot be easily seen while taking a reading or observation.

✨The vapour pressure of water is high. The vapour in the vacuum space makes it hard to read the observation.
