Corn oil has a density of 0.7 g/cm3. Water has a density of 1.0 g/cm3. A piece of plastic with a density of 0.9 g/cm3 will sink in corn oil and float to the top of the water.

Explanation:

Density is a unit that let us know the quantity of mass that a substance has per unit of volume. In a solution, the component with lower density will float, and be on the surface.

If we compare the densities of corn oil and a piece of plastic, the plastic will sink because its density ( 0.9 g/cm³ )is higher than the one of the corn oil (0.7 g/cm³).

In the case of the water, the plastic will float to the top because its density ( 0.9 g/cm³) is lower than the one of water (1.0 g/cm³).

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
