A pencil lead made of graphite is used to write on paper. What property of graphite explains why the marks are left on the paper?
Which statement is true about the mechanical strength of a single graphene sheet compared to bulk graphite?
Which allotrope of carbon has layers of hexagonally arranged atoms with delocalised electrons between the layers?
Why does graphite conduct heat well along the layers?
Why is graphite considered chemically stable in many environments but can still be oxidised at high temperatures in air?
Which property of graphite makes it useful as a material for high-temperature crucibles and refractory parts?
A sample of graphite is heated strongly in air and slowly oxidises to carbon dioxide. What does this tell you about the bonding in graphite?
What experimental observation would indicate that a carbon sample is composed of graphene-like layers that slide easily?
Why are graphite electrodes sometimes replaced during electrolysis of molten salts?
How does the presence of oxygen-containing groups on the surface of graphite (e.g., after oxidation) affect its behaviour in composite materials?
Graphite is used as a moderator (neutron absorber) in some nuclear reactors. Which property is most relevant to this use?
