Question

A solid block of iron sinks in fluid A but floats in another liquid B. What can be inferred about the properties of the fluids?

• A. Density of fluid A > Density of fluid B
• B. Density of fluid A = Density of fluid B
• C. Density of fluid A < Density of fluid B
• D. Temperature of Fluid A > Temperature of fluid B

Answer 1

The correct option is C

Density of fluid A < Density of fluid B

Since we know that 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, density of fluid B must be greater than iron and thus also greater than water.
