- 10. regulate flow in hydraulic systems
- 12. makes molecules moves faster and have more kinetic energy
- 13. the particles move less than a gas
- 15. this body system is hydraulic because it pumps blood
- 17. a force exerted on or against an object

Down
- 1. boats collect this water to keep the boat steady
- 2. a system that uses pressurized liquid
- 4. this body system is pneumatic because it moves oxygen and carbon dioxide through the body
- 5. a simplified word for negatively buoyant
- 6. a gas that has had its pressure increased by the reduction of its volume
- 7. a fluid exerts more pressure at greater depths
- 8. a simplified word for positively buoyant
- 9. the particles are moving rapidly because they have a lot of room in their container
