Why does the schottky defect decrease the densit of a solid?
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.
What phase of matter has the greastest density for most substances?
Solids are the densest state of matter for most substances. The variation of density for solids is typically very small.
What Density trend period 3 elements has?
The density of period 3 elements (sodium to argon) generally increases from sodium to silicon, reaching a peak at silicon. After silicon, the density decreases as you move to phosphorus and then to sulfur, before slightly increasing again with chlorine and argon. This trend is influenced by atomic structure, atomic mass, and the arrangement of atoms in solid forms. Overall, while there are fluctuations, the general trend shows an increase followed by a decrease in density across these elements.
Why does solid water (ice) float when placed in liquid water?
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.
Is toothpaste a solid or a gas or liquid?
Toothpaste is actually a solid. It is a solid that acts like a liquid.
Density of solid?
Density is weight (mass actually) divided by volume.
What area indicates a dramatic decrease in material density inside the earth?
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.

When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
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.
How does the process of melting and freezing affect the physical properties of a substance?
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.
Why does the volume of a heated solid decrease?
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.
Which Material forms crumbly crystals and has a melting point of 16.6 Celsius has a low density in solid form?
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.
How do find density if only mass is given of a rectangular solid?
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.
What are the three forms of matter in order of density?
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).
What phase of matter has the greastest density for most substances?
Solids are the densest state of matter for most substances. The variation of density for solids is typically very small.
In determining the density of an unknown solid it was immersed in water if a portion of the sample sticks out the water how will this effect the calculation of the density?
this will cause the density to be lower than it actually is because it does not displace the full amount of water it should
