what statment correctly describes a difference between graphene and graphite

Graphene is a two-dimensional material that is similar in structure to carbon nanotubes, but with some key differences. Graphene is made up of atoms arranged in a hexagonal lattice, just like carbon, but its properties are different due to its unique shape.

One of the main differences between graphene and graphite is their electrical conductivity. Graphene has an electric conductivity of about 1.3 x 10^-6 S/m, while graphite has an electrical conductivity of around 2.4 x 10^-7 S/m. This means that graphene can conduct electricity much faster than graphite.
Another important difference between the two materials is their mechanical strength. Graphene has a tensile strength of about 12 gigapascals (GPa), which is much higher than the tensile strength of graphite, which is around 1 gigapascal (GPa). This makes graphene more resistant to deformation and breakage than graphite.
Additionally, graphene has a high surface area to volume ratio, which means that it has many fewer atoms per unit area compared to graphite. This property allows for better contact between the material and other surfaces, making it useful for applications such as electronics and energy storage.
Despite these differences, there are also similarities between graphene and graphite. Both materials are hydrophobic, meaning they repel water and other liquids. They also both have a low melting point, which makes them suitable for use in extreme temperatures.

In conclusion, while there are certainly differences between graphene and graphite, both materials have unique properties that make them valuable in various applications. From their high electrical conductivity to their high mechanical strength, graphene offers many advantages over traditional materials. As researchers continue to explore new ways to manipulate and control graphitic structures, we can expect to see even more exciting developments in the field of carbon-based materials.
