Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the thermodynamic stability?The most stable allotrope of carbon under standard conditions
2. What is the anisotropic conductivity?Electrical and thermal conductivity is significantly higher parallel to the graphene layers
3. What is graphite and why is it called "slippery black stuff"?Graphite is a special form of carbon that is black and can slide easily between its layers, which is why it feels slippery. Its layers are made of carbon atoms in a hexagonal pattern, and the weak bonds let the layers move past each other.
4. How does graphite help pencils write?In pencils, graphite is mixed with clay and packed into a stick. When you write, the graphite leaves a thin line on paper because it is soft and can be rubbed off.

Crystalline Allotrope: A distinct solid form of an element with a specific atomic arrangement and crystal structure.
Anisotropic: Having properties that differ in direction, such as conductivity varying with orientation.
Thermodynamic Stability: The state of lowest free energy under given conditions, indicating resistance to change.
