Question

The density of a certain solid object is greater than the density of the liquid. If it is placed in water, the object will :

• A. sink
• B. expand
• C. float
• D. contract

Answer 1

The correct option is A sink

When solid is placed in water, the density of solid decides if it will float or sink in water.

If the density of solid is higher than liquid water it sinks because according to Archimedes principle, the buoyancy force is not enough to hold it in place.

i.e. if solid density > liquid - sinks

if solid density < liquid - floats

Hence the correct option is A.
