When compared with water, mercury is preferred as a thermometric liquid because
has a higher density
has lower specific heat capacity
exhibits anomalous thermal expansion
contains molecules which have very strong adhesive forces
Vysvetlenie
Specific Heat Capacity of mercury and water are 0.14 Jg\(^{-1}\)C\(^{-1}\) and 4.186Jg\(^{-1}\)C\(^{-1}\) respectively.
