What planet has a density of less than 1?

Answer 1

You mean density less than 1 gram per cubic centimeter. The definition of the SI unit: Density of water is 1000kilograms per cubic, that is 1 gram per cubic centimeter. So, a material with a density less than water means that it swims in water and does not sink.

Answer 2

A lot of things have lower density than water. Water has an uncommon property in that its solid state (ice) has lower density than its liquid state, which is why ice floats; with most substances (such as iron), the solid state is denser than the liquid state.

Essentially, anything that floats in water as a solid is less dense than water. Boats float not because the steel or wood in on of themselves are lighter, but the shapes boats are made let them carry air below the water line (their hulls keep the water from displacing the air), and the air balances out the density of the solid materials in the boat enabling them to float. If too much water takes on a boat made of steel or other substances more dense than water, they sink.

Oil is another substance which is has lower density than water; this is why oil tends to float on the surface of water.

Answer 3

Saturn has a density of less than 1 g/cm³, making it the only planet in our solar system with a density lower than water. This is due to its composition of primarily hydrogen and helium gases, along with smaller amounts of other materials.

Answer 4

I think it is Saturn because I answered that on a test and got it right

Answer 5

Anything that floats on water:- Oil, ice, wood etc' - because fresh water has a density of 1.

I think

Answer 6

Oil has a lower density than water, as it floats on top.

Answer 7

Saturn
