Why is mercury a more suitable liquid for thermometer than water and alcohol?

Non sticky to the glass surface
Because of shining its level can be easily seen
Boiling point is high
Being metal, coefficient of expansion is high
Above all, its angle of contact with glass is obtuse and so its meniscus is convex.

glass.Mercury has a high boiling point of about 357oC and can be used to measure high temperatures unlike alcohol which has a low boiling point of about 78oC.So mercury is used instead of alcohol in most theremometres.
