FLOAT
Oil is denser than cork, so the cork would float.
Corn syrup because corn syrup is denser than water.
Oil will sink in water, so is the least dense.
The ice will float. It is less dense than the corn oil. But as the ice melts, the water, which is more dense than the corn oil, will find its way to the bottom of the glass. That's with the oil at room temperature.If the oil is hot, the ice cube will melt quickly. And if it is so hot the water vaporizes, it will cause steam bubbles that snap and pop and spray hot oil all over. Very dangerous.
Mercury is a heavy metal, it will sink in sea water.
corn oil is made out of germ of corn.
1. The density of mercury is 13 534 kg/m3.2. Mercury sink in water.
Gold is more dense than mercury
Lead floats in mercury.
In water mercury would sink very quickly as it is very heavy. Keep in mind that part of mercury dissolves in water and is extremely poisonous.
Corn oil is all fat. There are no glucose sugars in corn oil or any other oil.
