kinetic theory Flashcards
1
Q
what is kinetic theory?
A
it describes how particles move in solids, liquids and gasses.
2
Q
what is kinetic energy?
A
the energy an object has because of its movement.
3
Q
what are the three states of matter?
A
solids
liquids
gasses
4
Q
what’s the qualities and particle arrangement of a solid?
A
- strong forces of attraction hold the particles close together in a fixed position
- they have a regular arrangement
- they don’t move, the vibrate where they are
5
Q
what’s the qualities and particle arrangement of a liquid?
A
- weaker attraction between the particles than in a solid
- particles are close together, but they move around and past eachother
- irregular arrangement
- more energy in particles than in particles of a solid
- they move in random directions at low speeds
6
Q
what’s the qualities and particle arrangement of a gas?
A
- almost no forces of attraction between the particles
- particles have more energy than in a solid or liquid
- they are free to move
- travel in random directions at high speeds
