**Physical Properties of Graphite**
- **Hardness**: Graphite has a hardness of 1 to 2 on the Mohs scale, making it very soft and slippery. It can easily be scratched with a fingernail.
- **Streak**: The streak of graphite is typically a dark gray to black color. It leaves a mark when rubbed on paper or other surfaces, which is one reason it is used in pencils.
- **Specific Gravity**: The specific gravity of graphite ranges from about 2.1 to 2.3, indicating that it is denser than many common minerals.
- **Mass**: The mass of graphite can vary substantially based on the sample size; however, its density is relatively consistent with the specific gravity mentioned above.
- **Float/Sink**: Graphite is denser than water, causing it to sink when placed in water.
- **Cleavage/Fracture**: Graphite exhibits perfect cleavage in one direction, allowing it to break easily along flat planes. This is indicative of its layered structure.
- **Crystal Shape**: Graphite typically forms in hexagonal crystals and has a platy or flaky appearance due to its layered structure. The individual layers can slide over one another easily, contributing to its lubricating properties.
Overall, graphite is a unique mineral with distinct physical properties that make it valuable in various applications, such as lubrication and as a conductor of electricity.
