All substances are dense. The density of some substances is greater than that of others. For example, the density of the earth's core material is greater than the density of the vacuum around Pluto. I think you're fishing for Osmium.

∙ 15y agoThis is something of a subjective question. Hydrogen atoms are the least dense, having only one electron per atom. Density varies upward from there, throughout the Periodic Table.

What is determined by the number of particles of a substance in a solution?
Heat is the speed of the particles the higher the speed the higher the heat. Density or state of matter is the distance between the particles the closer the particles the higher the density, the density of the particles determines the state of matter here they are from most dense to least dense; Solid, Liquid, Gas, and Plasma. the temperature (heat) of a substance can also determine the state of matter a substance is with higher heat at lower densities. PS the density/state list does not apply to water. PS Quantum state is not currently an official state yet, it would be the most dense and at the lowest temperature.
Which substance has the least density--substance ''a'' weighs 40.2 grams and has a volume of 5.7 cm3 and substance ''b'' has a volume of 6.3 cm3 and weighs 42.0 grams?
Density = mass/volume. Density(A) = 40.2/5.7 = 7.05 gcm-3 Density(B) = 42.0/6.3 = 6.67 gcm-3 So B is less dense.
What is the density of an unknown substance that has a mass of 100 g and a volume of 5 ml?
The density is 100/5 = 20 g/ml .That is some unusual and wonderful stuff you have there.The two most dense elements are-- osmium . . . 22.59-- iridium . . . . 22.56Also, the density of gold is 19.3 .
Where is the least dense layer at in water?
Well the density throughout the whole water substance is the same, adding substances increases its density the part added then spreads throughout the water
What substance is least dense rubber copper wood or mercury?
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
What natural substance is the most dense and what is its density?
Osmium is the densest element in nature at a density of 22.61
What is the most dense liquid substance?
Mercury, with a density of 13.590 Kg/m3
How does the density of most substances change when they are heated?
generally, the density of a substance decreaces when heated, with the exception of ice, which is less dense than water.
If you place a less dense substance into another substance with a greater density what happens?
It floats.
What is relation between viscocity and density?
The more dense a substance is, the more viscous it is.
Why is knowing the density of a substance is important for daily life?
to see how dense an object is
What is the relationship between object density the liquid density and the tendency of the object to float?
A less dense object or any other substance will float on a more dense liquid.
What is the relationship between an objects density and the liquid density and the tendency of an object to float?
A less dense object or any other substance will float on a more dense liquid.

What is the density of a substance determine?
It seems that the phrase you are looking for is "physical property". Density depends on several factors, such as: is the substance a solid, liquid or gas (the same substance will have vastly different densities at different states, but density is still a physical property of that substance); what temperature is it being measured at (most substances expand and become slightly less dense when heated); among others.
How do you determine if a substance is more dense or less dence?
Density is measured and expressed as the mass to volume ratio. To determine what the density of a substance you measure its mass and divide that number by its measured volume (or you can look up the density based on what composes it). Then, using the same units, do the same for another substance. The substance with the larger number is more dense, has more mass per volume, than the substance with the lower number, and the same in reverse with respect to less density.
When sound travels in gas is it more dense or less dense?
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
