The maximum density of water occurs at a temperature of 4°C
If an objects density is greater than the waters density it will sink but if it's density is less than the waters density it will float
Steel has the greatest density of the three.
Sink.
Mercury has the greatest density as a liquid in room temperture.
The Earth has the greatest average density, of all the planets.
Same as sanitary waters.
Fats (lipids) have the greatest calorific density, whether they are oils or animal fats.
In 1870, the area with the greatest population density was the city of Manila in the Philippines.
Oil is heavier than water so it sinks to the bottom.
Salinity (how much salt) of the water and low temperatures
it is osmonium.
