**Mass and Volume Shape and Length Shape and Size Color and texture**

A student is given an unknown substance and has to calculate the density. Which physical properties must first be determined? B Mass and Volume Shape and Length Shape and Size Color and texture

3
All three cylinders pictured above have the same volume. Which statement best describes the relationship between the densities of the cylinders and their contents? 6.6B Cylinder R is denser than Cylinders S and T. Cylinder T is denser than Cylinder R but less dense than Cylinder S. Cylinder S is less dense that Cylinder T and denser than Cylinder R. Cylinders R and T have the same density.

**A student combines Liquid A and Liquid B in a beaker**

A student combines Liquid A and Liquid B in a beaker. The student stirs the liquids and observes that the liquids do not form a solution. Further observation reveals the Liquid A rises to the surface and settles on top of Liquid B. What can the student conclude about Liquid A? B Liquid A is denser than Liquid B. Liquid A is less dense than Liquid B. Liquid A and Liquid B have the same density. Liquid A must be water.
