|
physical property |
anything about a substance or objects that we can observe or measure without changing it's physical composition |
|
|
physical properties |
include color, density, hardness, crystal form, texture, and physical state |
|
|
why do we use physical properties ? |
to help us identify substances, classify them, and most importantly, determine the best material to use for a given task |
|
|
can changes effect the shape or state of material ? |
yes, any change or arrangement of the matter in a material or object is physical change. |
|
|
physical change |
any arrangement of the matter in a material or object |
|
|
most common forms of matter |
solid, liquid, and gaseous state |
|
|

|
|
how do people use physical change ? |
electrical energy: huge steam turbine generators located in electrical power plants |

|
chemical change |
occurs when atoms of different substances break apart and combine in diff ends ways |
|
|
chemical change |
occurs when atoms of different substances break apart and combine in diff ends ways |
|
|
using properties of matter to solve problems |
ex. bulletproof vests are often made of a substance called Kevlar, has the physical properties of strength and flexibility |
|
|
conservation of matter |
• physical and chemical changes occur all around us • ex. water evaporates, wood burns, frost forms on cold surfaces |

|
nuclear change |
occurs when an atom's nucleons emits or absorbs a nuclear particle or Ray. splitting the nucleons into smaller nuclei is also a nuclear change |

occurs when an atom's nucleons emits or absorbs a nuclear particle or Ray. splitting the nucleons into smaller nuclei is also a nuclear change |
|
|
nuclear changes |
• include process where larger nuclei split into smaller nuclei or very small combine to form a larger nucleus |

|
changes of state |
• the water changes physical states but remains the same substance • when matter changes from one state to another, we call this result a phase change it change of state - liquid, Ice, water, and steam are all composed of water molecules |
