What's the meaning of "more dense"?

Question

does it floats or sink???

Answer 1

The molecular compound of the object has more atoms in it to make it more dense.

Answer 2

This means that it has a greater mass (Heavier) than another substance of equal volume.

(Water density = 1g/mL. Mercury = 13.6g/mL ...Much more dense than water.

Gasoline = 0.750g/mL...Less dense than water.

(Gasoline will float on water...Less dense.

Mercury will sink...more dense).

Answer 3

that means that it is the same size but contains more matter.

Answer 4

denser

Answer 5

simply put...the more dense object sinks...for example, if you drop a wine cork into water if floats b/c it is less dense than the water...if you drop in a piece of lead, it will sink b/c it is more dense....the subatomic particles are more numerous and closer together in the dense material

Answer 6

Density is mass/volume.

Water, for example, in its liquid state has a density of 1 g / ml. This means that 1 ml of water weighs 1 g (at STP).

Any compound that weighs more than 1 g for a volume of one ml is "more dense" than water.

If you place two compounds that are insoluble together, the less dense compound will float on the more dense molecule.

When water freezes to form ice the volume occupied by the water molecules increases, the mass stays the same, so the density decreases (ice weighs less then 1 g / ml). This is why ices floats on water.

Answer 7

Density = mass divided by volume

If something is more dense then the mass is larger for the same volume.  If it is denser than the liquid it is dropped into it will sink, if it is less dense than the liquid it will float.
