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? 6.6B
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.
