larger crystals
The crystalline structure of graphite and diamond are very different.
Diamond is more dense than coal. This is because diamond has a more tightly packed crystal structure, making it denser compared to coal which is less compact.
No. Diamond has a specific gravity of 3.6, which is above average. Morganite, which is a beryl gem, has a specific gravity of 2.8.
Diamond has a greater density than graphite because it has a crystal structure where each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement, making it tightly packed and more dense. In contrast, graphite has a layered structure with weak forces between the layers, resulting in a lower density.
Diamond is more stable than graphite due to its strong covalent bonds, requiring more energy to break these bonds during combustion, resulting in less heat evolution. Graphite has weaker van der Waals forces between its layers, making it easier to break apart and leading to more heat evolution during combustion.
Graphite is less dense than diamond, due to the differences in crystal structure.
Yes, graphite is more common than diamond.
Graphite is denser than charcoal, and not as easily smudged.
Graphite can be scratched by materials that are harder than it, such as diamond and tungsten.
A diamond is a solid, while water is a liquid.
No, pure carbon (in the form of graphite or diamond) is denser than water, so it sinks in water. However, carbon can float if it is in the form of a lightweight structure like graphene aerogel.
Of course less denser, because a gas is always less denser than liquid.
The crystalline structure of graphite and diamond are very different.
The specific gravity of graphite is around 2.2 to 2.3, which means it is denser than water. This property allows graphite to sink in water rather than float.
Graphite is a better conductor than diamond because graphite has delocalized electrons in its structure that can move freely along its layers, allowing for better electrical conductivity. In contrast, diamond has a tightly bound structure with no free electrons, leading to poor electrical conductivity.
For example, comparing olive oil with ethanol the alcohol is less denser.
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
