Ch 7 Kinetic Model of Matter# Flashcards
Describe movement of particles in solid.
Particles in solid vibrate vigorously at fixed positions.
Describe movement of particles in liquid.
Particles in liquid slide past each other over short distances.
Describe movement of particles in gas.
Particles in gas moves freely and randomly at high speeds.
Describe arrangement of particles in solid.
Particles in solid are arranged in an orderly manner.
Describe arrangement of particles in liquid.
Particles in liquid does not have a fixed arrangement.
Describe arrangement of particles in gas.
Particles in gas does not have a fixed arrangement.
Describe space between the particles in solid.
Particles in solid are packed closely together.
Describe space between the particles in liquid.
Particles in liquid are packed closely together.
Describe space between the particles in gas.
Particles in gas are far apart from one another.
Describe the forces of attraction between the particles in solid.
There are strong forces of attraction between the particles in solid.
Describe the forces of attraction between the particles in liquid.
There are strong forces of attraction between the particles in liquid.
Describe the forces of attraction between the particles in gas.
The forces of attraction between the particles in gas are negligible.
Explain why solid has a fixed shape. (using kinetic particle model)
Particles of solid are arranged in an orderly manner and can only vibrate vigorously at fixed positions.
Explain why liquid does not have a fixed shape. (using kinetic particle model)
Particles of liquid does not have a fixed arrangement and can slide past each other over short distances.
Explain why gas does not have a fixed shape. (using kinetic particle modelr)
Particles of gas does not have a fixed arrangement and can move freely and randomly at high speeds.
