Question

why is mercury only used in hydrometer

Answer 1

Hey mate here is your answer,

We use mercury only in hydrometer because

Mercury is the only metal which is in liquid state in room temperature.

It expands and contracts according to the temperature and pressure.

These specific characteristics of Mercury made it ideal for using in various instruments in which we can include Hydrometer.




Hope this helps ❤
