Text Solution
Verified by Experts
The correct Answer is:
B
Lighter substances (having lower density) float while heavier substances (having higher density) sink. Hence, gold having density 19.3 g/`cm^(3)` will sink in mercury having density 13.60 g/`cm^(3)` while cork having density 0.24 g/`cm^(3)` will float in alcohol having density 0.79 g/`cm^(3)`.
