What objects have the highest density?
The density, or more precisely the volumetric mass density, of a substance is its mass per unit volume (denoted in kg/m3). In space, the densest object observed to date is a neutron star — the collapsed core of a giant star can be twice as massive as our Sun.
Which liquid has high density?
mercury
So in that the liquid which has the highest density is mercury. It is the only metal which exists as liquid in room temperature other metals are hard and rigid and exist in solid phase. It has a density of about 13.546 grams per cubic centimeter.

What does having a high density mean?
High density used to describe something that has a high concentration. High denotes big, large or soaring or elevated. The word density means bulk of a substance. It refers to the concentration or the amount or quantity of something. Density could also mean mass, massiveness, solidity, thickness or tightness, heaviness, crowdedness and frequency.
Which has a higher density?
Earth has the highest density of any planet in the Solar System, at 5.514 g/cm 3. This is considered the standard by which other planet’s densities are measured. In addition, the combination of Earth’s size, mass and density also results in a surface gravity of 9.8 m/s².
Which is the material with highest density?
Basalt is the type of rock with the highest density. With an average value around 3 grams per cubic centimeter, it’s not even close to that of the metals, but it’s still heavy.
What is the definition of high density housing?
The definition of high-density housing in the dictionary is housing with a higher population density than the average, typically blocks of flats, and tower blocks.
