One special advantage of alcohol over mercury as a thermometric liquid is its?
low density
low freezing point
high specific
low boiling point
Paliwanag
The low freezing point of alcohol, -115°c enable low temperatures to be measured. mercury freezes at 39°c, and cannot be used in countries like Russia where winter temperatures of -40°c are common
