Chapter Two, Lesson One: States of Matter Flashcards
solid
A solid has a definite shape and a definite volume.
crystalline solids
Solids that are made up of crystals are called crystalline solids.
amorphous solids
In amorphous solids, the particles are not arranged in a regular pattern.
liquid
A liquid has a definite volume but no shape of its own.
fluid
A liquid is also called a fluid, meaning a “substance that flows.”
surface tension
Surface tension is an inward force, or pull, among the molecules in a liquid that brings the molecules on the surface closer together.
viscosity
Another characteristic property of liquids is viscosity, or a liquid’s resistance to flowing.
gas
A gas has neither a definite shape nor a definite volume.
pressure
The pressure of the gas is the force of its outward push divided by the area of the walls of the container.
