Properties of Solids, Liquids, and Kinetic Molecular Model

Vocabulary flashcards covering the properties of solids and liquids, crystalline vs. amorphous solids, temperature effects on particle kinetic energy, and assumptions of the Kinetic Molecular Model.

Particle Motion

Refers to how fast and freely particles move within a substance.

Particle Spacing

Refers to how close or far apart particles are from each other.

Intermolecular Forces

The attractive forces that determine how strongly particles attract each other.

Crystalline Solid

A type of solid where particles are arranged and organized in a specific, orderly manner, such as a table or chair.

Amorphous Solid

A type of solid with a fixed shape and volume where particles are not arranged in a specific manner, such as rubber or glass.

Solid Properties

Characterized by tightly packed particles in an orderly arrangement, vibrating in fixed positions, having definite shape, definite volume, high density, and being almost incompressible.

Liquid Properties

Characterized by particles that remain relatively close together but move and slide past one another, having definite volume, no definite shape, medium density, fluidity, and slight compressibility.

Kinetic Energy and Temperature Relationship

As temperature increases, the average kinetic energy of particles increases, causing particles to move faster.

Kinetic Molecular Model Gas Assumption 1

Particles are in constant random straight motion.

Kinetic Molecular Model Gas Assumption 2

The volume of individual particles is zero and they are separated by great distances.

Kinetic Molecular Model Gas Assumption 3

Particles collide with container walls or each other very rapidly and elastically, ensuring total energy remains constant.

Kinetic Molecular Model Gas Assumption 4

No forces exist between particles.
