What are the different states of matter and how are their particles oriented? List 2 fluids in the body and describe their function/purpose. What is the difference between high and low viscosity? Give 2 examples of a fluid with high viscosity and 2 with low viscosity. What are the 6 factors that affect viscosity? Briefly explain them. What is the formula to calculate density? What are the units we use? What does a hydraulic system use to create mechanical motion? What does a pneumatic system use to create mechanical motion? Explain the similarities and differences between hydraulic and pneumatic systems. What is an oil spill? Describe 2 ways in which we clean oil spills and the pros and cons of each. What are the effects of oil spills on the environment? Why is it better to have an oil spill on land rather than on water?
Understand the Problem
The question is requesting definitions and explanations of various concepts related to fluids, including properties of fluids, different states of matter, and the impact of oil spills on the environment. It seeks detailed information that can typically be found in a science textbook.
Answer
Fluids flow like liquids and gases; density is mass per volume. Viscosity measures flow resistance. Buoyancy opposes weight: positive floats, negative sinks, neutral is stable. Hydraulic systems use liquids, pneumatic use gases for motion. Oil spills pollute ecosystems.
The search results provide detailed definitions and explanations for terms such as fluids, density, buoyancy, and viscosity. They describe fluids as matter that flows, like liquids and gases, and density as mass per unit volume. Buoyancy is the upward force exerted by a fluid, opposing an object's weight. Positive buoyancy means an object floats, negative means it sinks, and neutral means it stays submerged at a constant depth. Viscosity involves a fluid's resistance to flow, with high viscosity indicating thicker fluids and low viscosity indicating thinner ones. An oil spill describes the release of liquid petroleum into the environment, and methods like chemical dispersants and skimming are used for cleanup, each having pros and cons. Hydraulic systems use liquids, and pneumatic systems use gases to create motion. The effects of oil spills include environmental pollution and habitat destruction.

More Information
Buoyancy was famously used by Archimedes to determine if a crown was made of pure gold, leading to his foundational principle. Viscosity affects things like oil flow in engines and syrup dripping on pancakes.
Tips
Mixing up viscosity with density can lead to confusion; remember viscosity is about flow, while density is mass in space.
