Density of Liquids

Olive Oil: .918 kg/m3
Soy Sauce: 1000 kg/m3
Honey: 1360 kg/m3



The order of substances would have to be olive oil on top, soy sauce in the middle, and honey on the bottom. This is because olive oil has the smallest density (.918 kg/m3) as compared to soy sauce (1000 kg/m3) and honey (1360 kg/m3). The substances are able to layer because the least dense substance floats on top of the denser substances. The most dense cannot float on a less dense substance and therefore goes to the bottom. Temperature could also possibly affect the order of layering.
