A. low density
B. low freezing point
C. high specific
D. low boiling point
Correct Answer:
Option B – low freezing point
Explanation
The low freezing point of alcohol, -115°c enables 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
