- 3. At this extremely low temperature, molecular motion comes very close to stopping. Since there is almost no kinetic energy being transferred from one atom to another, the atoms begin to clump together
- 5. highly charged particles with extremely high kinetic energy
- 6. particles are packed tightly together so they don't move much
- 7. the particles have a great deal of space between them and have high kinetic energy
- 9. the particles are more loosely packed than in a solid and are able to flow around each other, giving the liquid an indefinite shape.
- 10. The process of a liquid becoming a gas is

- 1. process of a gas becoming a liquid
- 2. , which are in turn made up of protons, neutrons and electrons.
- 4. the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
- 8. the "stuff" that makes up the universe — everything that takes up space and has mass is
