Water's density increases with reducing temperature then at 4ºC, it decreases, the water expanding as it freezes. This is a molecular property, and I think it is unique to water.
The defect forms when oppositely charged ions leave their lattice sites, creating vacancies. These vacancies are formed in stoichiometric units, to maintain an overall neutral charge in the ionic solid. The vacancies are then free to move about as their own entities. Normally these defects will lead to a decrease in the density of the crystal.
Solids are the densest state of matter for most substances. The variation of density for solids is typically very small.
mass/volume=density
Solid water (ice) floats on liquid water because of its lower density. When water freezes, its molecules arrange in a hexagonal lattice structure that occupies more space than in the liquid state, resulting in a decrease in density. This lower density allows ice to remain buoyant and float on the surface of liquid water.
Toothpaste is actually a solid. It is a solid that acts like a liquid.
Density is weight (mass actually) divided by volume.
The outer core of the Earth, which consists of liquid iron and nickel, represents a dramatic decrease in material density compared to the solid inner core. This decrease in density is due to the transition from solid to liquid material, resulting in a noticeable reduction in density within the outer core.

A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
When a substance melts, it changes from a solid to a liquid state, causing an increase in flexibility and a decrease in density. This process also typically involves an increase in temperature. On the other hand, when a substance freezes, it changes from a liquid to a solid state, resulting in a decrease in flexibility and an increase in density. This process usually involves a decrease in temperature.
When a solid is heated, the molecules gain kinetic energy and vibrate more vigorously, leading to an increase in the space between molecules. This increased kinetic energy causes the solid to expand, which can result in a decrease in the overall density and volume of the solid due to the increased space between molecules.
This is acetic acid, a molecular solid. The low melting point indicates that it's not a network atomic solid or ionic solid, and the fact that it forms crystals rules out metals and amorphous soilds.
If this rectangular solid is actually in your possession, then you would measure it and calculate the volume, after which you can derive the density by dividing the mass by the volume. If it is not in your possession, then you are clearly being asked to call upon your psychic powers to solve this problem.
The three forms of matter in order of density is solid (most dense, bonds are strong to hold object together in a solid form), liquid (more dense than solids but less dense than gas, fills a container and forms to its shape), and gas (least dense of all forms of matter, a gas expands into available space in any direction and has no clearly defined form).
Solids are the densest state of matter for most substances. The variation of density for solids is typically very small.
this will cause the density to be lower than it actually is because it does not displace the full amount of water it should
Osmium is the solid element that has the highest density. Opposite of osmium is hydrogen which has the lowest density.
