Science - Chapter 7 Flashcards
Fluids
Materials that have no fixed shape and are free to flow, such as liquids and gases
Particle Theory of Matter
A theory that explains what matter is made of and how it behaves
Laminar Flow
A smooth patter of flow
Turbulent Flow
An irregular, mixing flow pattern
Eddy
An area of slower-moving fluid that occurs behind an obstacle
Streamlined
A smooth shape designed to decrease resistance to fluid flow
Flow Rate
A measure of how quickly fluids move; measured in a volume per unit time (for example, L/s or mL/min)
Viscosity
A measure of how easily a fluid’s particles are able to slide past one another
Cohesion
A measure of how strongly the particles of a fluid attract each other
Surface Tension
The strong attraction among the particles that form the surface of a liquid
Adhesion
The attraction between the particles of one substance and the particles of another substance
Fluid Mechanics
The study of fluids and how they behave when at rest and when moving
Fluid Dynamics
A part of the study of fluid mechanics concerned with how fluids move
Aerodynamics
A part of fluid dynamics concerned with how gases move
Hydrodynamics
A part of fluid dynamics concerned with how liquids move
