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 experimental approximations?Quark-gluon plasma and certain charge transport in graphene exhibit near-perfect fluid behavior
2. Why do scientists use the idea of a perfect fluid?Scientists use the perfect fluid idea to make math easier. By ignoring friction and heat, they can study the basic rules of fluid motion before adding more real‑world details.
3. How is a perfect fluid different from a normal liquid?A normal liquid has friction that slows it down and can carry heat. A perfect fluid has no friction and no heat conduction, so it flows without resistance.

Viscosity: A measure of a fluid's resistance to shear flow; internal friction.
Thermal Conductivity: A material's ability to conduct heat energy.
Quantum Chromodynamics (QCD): The theory describing the strong nuclear force, which binds quarks and gluons together.
Quark-Gluon Plasma (QGP): A state of matter at extremely high temperatures and densities where quarks and gluons are deconfined.
