State Of Matter Flashcards
Gas aka
Vapor
The arrangement of molecules and how they behave determine
The state of the substance
Molecule definition
Group of atoms bonded together
Atom def
Small building block or unit of matter
Molecules in a substance _ to one another
Attached
Each molecule has energy associated with how much they
Move about within the substance
The amount of movement of molecules and the _ within the substance determines its state
Distance between the molecules
Solid, molecules tightly packed together and don’t
Move about much within a substance
Gas molecules are far apart and can
Move about freely within a substance
A solid has a _ structure
Fixed
A fixed structure aka
A definite state
A solids _ do not change (2)
Shape
Volume
Molecules in solid are packed close together in a
Particular pattern
In solids, molecules are able to _ but cannot break the structure
Vibrate back and forth in their places
Liquid does not have a
Defined shape
A liquid does have a fixed
Volume
The energy movement of liquids molecules causes them to
Overcome the attractive forces between them
Although liquid particles move freely, they are still
Relatively close to one another
Viscosity def
Speed at which molecules move in a liquid
_ is the resistance to flow
Viscosity
Viscosity is the resistance to
Flow
Viscosity is sometimes referred to as _ between molecules of the fluid
Friction
