Question

A block of iron sinks in fluid A but floats in fluid B, this is because fluid A is ________ than fluid B.

• A. more dense
• B. less dense
• C. bigger in size
• D. smaller in size

Answer 1

The correct option is B less dense

The sinking and floating of a body in a liquid is due to the difference in their densities. If the density of the body is greater than the liquid then it sinks and vice-versa. So the density of fluid B must be greater than iron and also greater than fluid A.
