3. What is not included in a hydraulic system?
4. Scientists and engineers have established a way to compare the density of a substance with the density of water. This is called ________ density.
7. Changes of pressure on the surface of a confined fluid are exerted equally throughout the fluid and at all points on the fluid's container. This is known as _____________
10. Evangelista Torricelli invented the mercury _____________ which consisted of a thick-walled glass tube filled with liquid mercury and sealed on one end.
12. Water pressure due to depth alone is called _________ pressure
14. If an amount of force is applied to a smaller area, the pressure of that object will be ______ than the pressure of the same force applied to a larger area.
16. Scientists and engineers have established a way to compare the density of a substance with the density of water. This is called ________ gravity.

1. __________ is the science of the transmission of forces and energy by liquids. It's mechanical advantage is calculated the same way as simple machines.
2. Fluid pressures in mechanical systems and pipes are measured with mechanical _________
5. The SI unit used to measure pressure in newtons per square meter is known as _________
6. The study of how fluids flow and how forces and energy are transmitted through fluid
8. The human __________ system can be compared to a hydraulics system because of the way pressure is used to pump blood through the body.
9. If temperature is constant, volume and pressure will have an inverse relationship. This is known as ______ law.
11. When water is flowing, is there higher pressure and flow coming from a lower bath tub faucet or a high shower head faucet?
13. If pressure is constant, temperature and volume will have a direct relationship. This is known as _______ law.
