A pycnometer is used for the measurement of________________________?
Correct answer: B. Specific gravity of a liquid
- A. Flow rate of molten metal
- B. Specific gravity of a liquid
- C. Composition of alloys
- D. Concentration of a solution
Explanation
A pycnometer holds a precisely known volume, so weighing the empty and filled vessel gives the liquid density and hence its specific gravity. It is not normally used to determine alloy composition or solution concentration directly.
