| States of matter are the PHYSICAL FORMS in which a substance exists. |
|
|
Term
| Three states of matter are: |
|
Definition
1. Solid (example- ice)
2. Liquid (example- water)
3. Gas (example- steam) |
|
|
Term
|
Definition
| Solid is a state of matter that has a definite SHAPE. |

| Liquid is a state of matter that definete VOLUME and takes the shape of its container. |
|

Term
|
Definition
| Gas is a state of matter that has NO definite shape or volume. The particles of gas move quickly. |

Definition
| Surface tension is the FORCE that acts on the SURFACE of a liquid. Different liquids have different surface tensions. |
|
|
Term
|
Definition
| Viscosity is a liquids RESISTANCE to flow. Example, honey flows more slowly than water, so honey has a higher viscosity than water. |

|
Definition
| Temperature is a measure of how fast the particles in an object are moving. The faster the particles are moving, the more energy it has, so the higher the temperature. |
|

Definition
| Pressure is the amount of FORCE EXERTED on a given surface area. |
|
|
Term
|
Definition
| State of change is the change of a substance from one PHYSICAL form to another. Example- water can undergo a change of state from liquid to gas to solid and back again. |
