phases of matter Flashcards
What is the arrangement of particles in solids?
Particles are tightly packed (close together), vibrating about a fixed position.
Solids maintain a definite shape and volume.
Do solids have a definite shape and volume?
Yes, solids have a definite shape and a definite volume.
This is due to the close packing of particles.
What is the kinetic energy of particles in solids?
The kinetic energy of particles is not great enough to overcome the attractive forces between the particles.
This results in a fixed position for the particles.
How are the particles arranged in liquids?
Particles are tightly packed but are far enough apart to slide over one another.
This allows liquids to take the shape of their container.
Do liquids have a definite shape and volume?
Liquids have an indefinite shape and a definite volume.
They adapt to the shape of their container while maintaining a fixed volume.
What is the kinetic energy of particles in liquids?
The kinetic energy of particles is great enough to overcome some of the attractive forces between the particles.
This results in the ability of particles to slide past one another.
What is the arrangement of particles in gases?
Particles are very far apart and move randomly and rapidly.
This leads to gases having no fixed shape or volume.
Do gases have a definite shape and volume?
Gases have an indefinite shape and an indefinite volume.
They expand to fill their container.
What is the kinetic energy of particles in gases?
The kinetic energy of particles is great enough to overcome all of the attractive forces between the particles.
This allows for rapid movement and randomness.
