P1: Particles Flashcards
What does density describe?
How closely packed the particles are in a solid, liquid or gas.
What does all matter contain?
Particles,
Describe the layout of particles in a solid.
Particles are tightly packed together in a regular structure
Describe the layout of particles in a liquid.
Particles are tightly packed but free to move past eachother. Disordered structure.
Describe the layout of particles in a gas.
Particles are spread out and move randomly at random speeds.
Describe the movement of particles in a solid.
Particles vibrate about fixed positions.
Describe the movement of particles in a liquid.
Particles move with random motion throughout the container.
Describe the motion of particles in a gas.
Particles move rapidly in all directions at random speeds, frequently colliding with eachother
