Across
- 4. matter composed of positively and negatively charged particles with
- 5. a diagram that shows the state of transitions a substance goes through as heat or energy is added
- 7. the phase/state transition from liquid to gas
- 9. Fixed volume but shape changes
- 11. the sum of the kinetic and potential energy of particles in an object
Down
- 1. when particles gain or lose thermal energy
- 2. caused by pressure change, occurs only at the surface of a liquid
- 3. stored energy
- 6. fixed volume and fixed shape
- 8. caused by a temperature change, occurs throughout a liquid
- 10. measure of the average kinetic energy and motion of particles
- 12. No fixed volume or shape
