Question

The density of a metal block is $2.7\times {10}^{3}kg/m^3$. It is immersed in water. State the situation.

• A. Sinks
• B. Floats
• C. Partially immersed
• D. No part immersed

Answer 1

The correct option is A Sinks

Any solid floats on water if its density is less than the density of water.

Or we can say the object will float on water if the relative density is less than 1.

Relative density = $\frac{Densityofmetal}{Densityofwater}=\frac{2.7\times {10}^3}{{10}^3}$

In this case relative density is 2.7, so it will sink.
