- 8. Type of energy related to the total kinetic energy of particles
- 9. What ice does on water because it is less dense
- 10. Heat transfer through moving fluids where warm fluid rises
- 11. State of matter with fixed volume but no fixed shape
- 13. Type of variable you measure that responds to your change
