Card preview (24)
Liquid
Particles packed but not as tightly, some light passes
Solid
Tightly packed particles, no light passes
Gas
Particles move freely, light passes
Plasma
Starts as a gas but then is ionized. No definite shape
Energy
Ability to do work
Thermal Energy
All the kinetic energy that makes a object
Evaporation
Change from liquid to gas
Sublimation
A solid changes instantly to a gas
Condensation
A gas changes to a liquid
Crystalline Solid
Atoms/ molecules are arranged orderly
Amorphous Solid
Atoms/ molecules in no certain order
Surface Tension
Force that acts on a liquid to change it into a spherical drop
Kinetic Energy
Energy that’s in motion
Heat
Causes a change in state
Endothermic Change
Energy required for MELTING
Exothermic Change
FREEZING
Fluid
Molecules can move past each other
Buoyant force
Force given off upward on an object floating on a fluid
Pressure
The total force given off per unit area of a surface
Archimedes principle
Buoyant force on an object in a fluid is the upward force equal to the volume weight
Pascal
Si unit of pressure
Pascals principle
Fluid in a container gives off the pressure off the equal intensity in all directions
Viscosity
The flow of gas and liquid resisted
Bernoullis principle
The velocity of a fluid in motion increases as the pressure of a moving fluid decreases
