| |
Thermal energy |
the sum of kietic energy and potential energy of the particles of a substance |
| |
heat |
movement of thermal energy from a substance at a higer tempurature to a substance at lower tempurature |
| |
energy |
the ability to cause change or work |
| |
matter |
anything that has mass and takes up space |
| |
density |
phsical property of matter that can be found by dividing the matters mass by its volume |
| |
state of matter |
pyisical property that describes a substance as a solidliquid, or gas |
| |
freezing point |
change of matter from a liquid state to a solid state |
| |
evaporation |
change of matter is the vaporization that occurs at the surface of a liquid |
| |
vaporization |
change of matter from a liqiud to a gas |
| |
condensation |
change of matter from a gas to a liqiud |
| |
melting point |
change of matter from a solid to a liqiud |
| |
boiling point |

| |
pressure |
amount of force applied per unit area on an objects surface;SI unitnis the pascal |
| |
Buoyant force |
upward force exerted on an object immersed in a fluid |
| |
Pascals principale |
states when force is applied to an confined fliud a increase in pressure is transmitted equally to all parts of the fluid |

matter that does not have a definate shape or volume |
| |
solid |
matter with a definate shape or volume |
| |
liquid |
matter witha definate shape but no definate volume |
| |
