| Term | Definition |
|
thermal energy |
the sum of the kenetic and potential energy of the individual particles of a substance |
|
heat |
movement of thermal energy from a substance at a higher temperature to a substance at a lower temperature |
|
energy |
the ability to move |
|
matter |
anything that has mass and takes up space |
|
density |
physical property that can be found by dividing the matter's mass and volume |
|
evaporation |
vaporization that occurs at the surface of a liquid molecules must be at or near the surface and at th right speed to evaporate |
|
boiling point |
vaporization that occurs below the liquid's surface or when water changes to gas |
|
Archimedes' Principal |
states that buoyant force on an object is equal to the weight of fluid displaced by the object |
|
Pascal's Principle |
states that when a force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts |
|
state of matter |
physical property that describes a substance as a gas, solid, or liquid |
|
freezing point |
the change from liquid to solid |
|
vaporization |
a change of matter from liquid to state |
|
condensation |
change of matter from a gas to a liquid |
|
melting point |
change of matter from a solid state to a liquid state |
|
pressure |
the amount of force applied per unit area on an object's surface |
|
buoyant force |
upward force exerted from an object immersed in a fluid |
|
gas |
matter that does not have a definite shape or volume |
|
solid |
has a definite shape and volume |
|
liquid |
has a definite volume but not a definite shape |
|
kinetic energy |
energy an object has due to its motion |
|
amorphous solids |
particles found in random arrangment |
