|
Matter |
Anything that takes up space and has mass. |
|
|
Solid |
Matter with a definite shape and volume. |
|
|
Liquid |
Matter that has definite volume but no definite shape. |
|
|
Viscosity |
A liquids resistance to flow. |
|
|
Surface Tension |
The uneven forces acting on the particles on the surface of a liquid. |
|
|
Gas |
Matter that does not have definite shape or volume. |
|
|
Thermal Energy |
Total kinetic and potential energy of all the particles in a sample of matter. |
|
|
Temperature |
Average kinetic energy of all the individual particles. |
|
|
Heat |
The movement of thermal energy from a substance at a higher temperature to one of a lower temperature. |
|
|
Melting |
The change from the solid state to the liquid state. |
|
|
Freezing |
The change from the liquid state to the solid state. |
|
|
Vaporization |
The change from a liquid to a gas. |
|
|
Condensation |
Particles move slowly enough for their attractions to bring them together, droplets of liquid form. |
|
|
Pressure |
Is equal to the force exerted on a surface divided by the total area over which the force is exerted. Pressure=force/area |
|
|
Buoyant Force |
The difference in pressure results in an upward force on an object immersed in fluid. |
|
|
Archimedes' Principle |
The buoyant force on an object is equal to the weight of the fluid displaces by the object. |
|
|
Density |
The mass divided by volume. |
|
|
Pascal's Principle |
An increase in pressure when force is applied is transmitted equally to all parts of the fluid. |
