Gases & Liquids
What is Diffusion?
The movement of particles
Volume
The amount of space occupied by an object
Fluid
A substance that can easily change shape
What Archemedes shouted When He Discovered Buoyancy
Eureka!
Viscosity
The resistance of a liquid to flow
What makes Particles move Slower?
A Lower Temperature
Equation for Density
Mass / volume
Ketchup
Non-Newtonian Fluid
Archemedes Discovered buoyancy when...
Water spilled out of a bathtub
Graduated Cylinder
A hollow cylinder that has markings on the side to measure water
An engine that Uses Liquids to move
Hydraulic
Formula for the Volume of a Rectangular Shape
Length x Width x Height
Non-Newtonian Fluid
A fluid that acts like a solid
An object Displaces...
As much water as it weighs
Viscometer
A tool that measures viscosity
An engine that uses Gases to move
pneumatic
Density
The mass of a substance per unit
Plasma
When extreme heat is applied to a gas so electricity can pass through it
Archimedes' Principle
A body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.
Flow Rate
How fast a liquid flows
Same Volume, Changeable Shape
Liquid
Volume for an Irregular Shape
Displacement
The Three Forms of Fluids
Gas, Liquid, & Plasma
Buoyancy
The upward force of a fluid on an object
Cohesive Force
Strong enough to keep the particles together, but weak enough to allow them to slide past each other
