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 key physical properties?Surface tension, viscosity, and density are defining characteristics of liquids
2. What is the scientific relevance?Liquids are fundamental to biological processes, chemical reactions, and numerous technological applications
3. Why do liquids keep the same volume but change shape?Liquids keep the same volume because their molecules stay close together, but they can move around each other, so the liquid can spread out and take the shape of the container.
4. How does surface tension work in liquids?Surface tension is the pull that molecules at the surface of a liquid have on each other, making the surface act like a stretched skin. It lets things like a paperclip float on water and creates water droplets.

Intermolecular Forces: Attractive or repulsive forces between adjacent molecules, influencing a liquid's properties.
Laminar Flow: A fluid flow regime characterized by smooth, parallel layers of fluid with no significant cross-stream mixing.
Non-Newtonian Fluid: A fluid whose viscosity changes when subjected to an applied stress or strain.
