# Archimede's Principle

## Homework Statement

An unknown fluid is placed in a bottle and then placed in a beaker of water where it displaces x amount of water. The unknown fluid is then frozen into a block and a greater proportion of this substance is now submerged, what does this say about the change in density?

## The Attempt at a Solution

Am I right in thinking the density increases, there is no mention of what happens to the volume of the substance or the volume displaced???

hi bobred!

$$\frac{V_0}{V}=\frac{\rho}{\rho_0}$$
what is confusing me is what happens to the unknown substance when it is frozen, does it expand or contract and therefore change the density $$\rho$$
