Desirable properties of good manometric liquid should have;
-> Low-freezing point.
-> High boiling point.
-> Non wetting characteristics.
-> Low surface tension.
-> Chemically inert.
-> Clear visible interface.
-> Ability to maintain density at various temperatures.
-> Low-freezing point.
-> High boiling point.
-> Non wetting characteristics.
-> Low surface tension.
-> Chemically inert.
-> Clear visible interface.
-> Ability to maintain density at various temperatures.

Should have high density to decrease the column height and due to which we can measure more range of pressure.

Why high surface tension required?

@Vinit.
Non-wetting and low surface tension are contradictory.
Non-wetting and low surface tension are contradictory.

Higher surface tension enables less wetting of the tube and so these type of liquids are desirable in manimeters.

Then why we use mercury as a manometric fluid?
I think the given answer is correct.
