Chapter 2: Kinetic Particle Theory Flashcards
What is the kinetic particle theory
All matter is made up of tiny particles that are in constant, random motion
Arrangement, movement and forces of attraction between particles in a solid
Arrangement: Very closely packed in an orderly manner
Movement: Vibrating about fixed positions
Forces of attraction: Very strong
Arrangement, movement and forces of attraction between particles in a liquid
Arrangement: closely packed in a disorderly manner
Movement: Sliding past one another freely throughout the lquid
Forces of attraction: Strong
Arrangement, movement and forces of attraction between particles in a gas
Arrangement: Very far apart in a disorderly manner
Movement: moving quickly and randomly
Forces of attraction: very weak
Differences between boiling and evaporation?
Evaporation occurs at any temperature below the boiling point and only at the surface of the liqud.
Boiling occurs only at the boiling point and throughout the liquid
Definition of diffusion?
The net movement of particles from a region of higher concentration to a region of lower concentration
Which states can undergo diffusion?
Liquid and Gas because particles are free to move in the liquid
Factors affecting rate of diffusion?
Molecular mass (heavier=slower)
Tenperature(kinetic energy=move faster)
