Water has a density of 1.0 g/ml and a test liquid has density of 1.1 g/ml. If you pour equal portions of the two liquids into a cup,what will happen ( assuming the two do not mix or create a chemical reaction)?
Since the test liquid is denser than water, theoretically the test liquid would sink, but since the difference is so minor, the liquid poured after may float on top of the other liquid.
